[ Upstream commit 4ed2f3545c2e5acfbccd7f85fea5b1a82e9862d7 ]
The error handling code of fsl_ifc_ctrl_probe is problematic. When
fsl_ifc_ctrl_init fails or request_irq of fsl_ifc_ctrl_dev->irq fails,
it forgets to free the irq and nand_irq. Meanwhile, if request_irq of
fsl_ifc_ctrl_dev->nand_irq fails, it will still free nand_irq even if
the request_irq is not successful.
Fix this by refactoring the error handling code.

If an error occurs after a successful tegra_powergate_enable_clocks()
call, it must be undone by a tegra_powergate_disable_clocks() call, as
already done in the below and above error handling paths of this function.
Update the 'goto' to branch at the correct place of the error handling
path.

[ Upstream commit 8878e46fcfd46b19964bd90e13b25dd94cbfc9be ]
If adapter's resetting bit is on, discard the packet but don't stop the
transmit queue - instead leave that to the reset code. With this change,
it is possible that we may get several calls to ibmvnic_xmit() that simply
discard packets and return.
But if we stop the queue here, we might end up doing so just after
__ibmvnic_open() started the queues (during a hard/soft reset) and before
the ->resetting bit was cleared. If that happens, there will be no one to
restart queue and transmissions will be blocked indefinitely.
This can cause a TIMEOUT reset and with auto priority failover enabled,
an unnecessary FAILOVER reset to less favored backing device and then a
FAILOVER back to the most favored backing device. If we hit the window
repeatedly, we can get stuck in a loop of TIMEOUT, FAILOVER, FAILOVER
resets leaving the adapter unusable for extended periods of time.

[ Upstream commit fd8d9731bcdfb22d28e45bce789bcb211c868c78 ]
mvneta does not support asymetric pause modes, and it flags this by the
lack of AsymPause in the supported field. When setting pause modes, we
check that pause->rx_pause == pause->tx_pause, but only when pause
autoneg is enabled. When pause autoneg is disabled, we still allow
pause->rx_pause != pause->tx_pause, which is incorrect when the MAC
does not support asymetric pause, and causes mvneta to issue a warning.
Fix this by removing the test for pause->autoneg, so we always check
that pause->rx_pause == pause->tx_pause for network devices that do not
support AsymPause.

[ Upstream commit 9bfe38e064af5decba2ffce66a2958ab8b10eaa4 ]
This is essentially exactly following the dma_wmb()/dma_rmb() usage
instructions in Documentation/memory-barriers.txt.
The theoretical races here are:
1. DXE (the DMA Transfer Engine in the Wi-Fi subsystem) seeing the
dxe->ctrl & WCN36xx_DXE_CTRL_VLD write before the dxe->dst_addr_l
write, thus performing DMA into the wrong address.
2. CPU reading dxe->dst_addr_l before DXE unsets dxe->ctrl &
WCN36xx_DXE_CTRL_VLD. This should generally be harmless since DXE
doesn't write dxe->dst_addr_l (no risk of freeing the wrong skb).

[ Upstream commit c65b52d02f6c1a06ddb20cba175ad49eccd6410d ]
As bcm6345_l1_irq_handle() is a chained irqchip handler, it will be
invoked within the context of the root irqchip handler, which must have
entered IRQ context already.
When bcm6345_l1_irq_handle() calls arch/mips's do_IRQ() , this will nest
another call to irq_enter(), and the resulting nested increment to
`rcu_data.dynticks_nmi_nesting` will cause rcu_is_cpu_rrupt_from_idle()
to fail to identify wakeups from idle, resulting in failure to preempt,
and RCU stalls.
Chained irqchip handlers must invoke IRQ handlers by way of thee core
irqchip code, i.e. generic_handle_irq() or generic_handle_domain_irq()
and should not call do_IRQ(), which is intended only for root irqchip
handlers.
Fix bcm6345_l1_irq_handle() by calling generic_handle_irq() directly.

[ Upstream commit 2641b62d2fab52648e34cdc6994b2eacde2d27c1 ]
Some Micrel KSZ8041NL PHY chips exhibit continuous RX errors after using
the power down mode bit (0.11). If the PHY is taken out of power down
mode in a certain temperature range, the PHY enters a weird state which
leads to continuously reporting RX errors. In that state, the MAC is not
able to receive or send any Ethernet frames and the activity LED is
constantly blinking. Since Linux is using the suspend callback when the
interface is taken down, ending up in that state can easily happen
during a normal startup.
Micrel confirmed the issue in errata DS80000700A [*], caused by abnormal
clock recovery when using power down mode. Even the latest revision (A4,
Revision ID 0x1513) seems to suffer that problem, and according to the
errata is not going to be fixed.
Remove the suspend/resume callback to avoid using the power down mode
completely.

[ Upstream commit 86d46fdaa12ae5befc16b8d73fc85a3ca0399ea6 ]
Refactoring of the Atari floppy driver when converting to blk-mq
has broken the state machine in not-so-subtle ways:
finish_fdc() must be called when operations on the floppy device
have completed. This is crucial in order to relase the ST-DMA
lock, which protects against concurrent access to the ST-DMA
controller by other drivers (some DMA related, most just related
to device register access - broken beyond compare, I know).
When rewriting the driver's old do_request() function, the fact
that finish_fdc() was called only when all queued requests had
completed appears to have been overlooked. Instead, the new
request function calls finish_fdc() immediately after the last
request has been queued. finish_fdc() executes a dummy seek after
most requests, and this overwrites the state machine's interrupt
hander that was set up to wait for completion of the read/write
request just prior. To make matters worse, finish_fdc() is called
before device interrupts are re-enabled, making certain that the
read/write interupt is missed.
Shifting the finish_fdc() call into the read/write request
completion handler ensures the driver waits for the request to
actually complete. With a queue depth of 2, we won't see long
request sequences, so calling finish_fdc() unconditionally just
adds a little overhead for the dummy seeks, and keeps the code
simple.
While we're at it, kill ataflop_commit_rqs() which does nothing
but run finish_fdc() unconditionally, again likely wiping out an
in-flight request.

[ Upstream commit 0a491167fe0cf9f26062462de2a8688b96125d48 ]
Most of the txpower for the ath10k firmware is stored as twicepower (0.5 dB
steps). This isn't the case for max_antenna_gain - which is still expected
by the firmware as dB.
The firmware is converting it from dB to the internal (twicepower)
representation when it calculates the limits of a channel. This can be seen
in tpc_stats when configuring "12" as max_antenna_gain. Instead of the
expected 12 (6 dB), the tpc_stats shows 24 (12 dB).
Tested on QCA9888 and IPQ4019 with firmware 10.4-3.5.3-00057.

Currently mtk_rng_runtime_suspend/resume is called for both runtime pm
and system sleep operations.
This is wrong as these should only be runtime ops as the name already
suggests. Currently freezing the system will lead to a call to
mtk_rng_runtime_suspend even if the device currently isn't active. This
leads to a clock warning because it is disabled/unprepared although it
isn't enabled/prepared currently.
This patch fixes this by only setting the runtime pm ops and forces to
call the runtime pm ops from the system sleep ops as well if active but
not otherwise.

AMD Rome systems and later support interleaving between three identical
ranks within a channel.
Check for this mode by counting the number of enabled chip selects and
comparing their masks. If there are exactly three enabled chip selects
and their masks are identical, then three rank interleaving is enabled.
The size of a rank is determined from its mask value. However, three
rank interleaving doesn't follow the method of swapping an interleave
bit with the most significant bit. Rather, the interleave bit is flipped
and the most significant bit remains the same. There is only a single
interleave bit in this case.
Account for this when determining the chip select size by keeping the
most significant bit at its original value and ignoring any zero bits.
This will return a full bitmask in [MSB:1].

[ Upstream commit 4925642d541278575ad1948c5924d71ffd57ef14 ]
In tests with two Lima boards from 8devices (QCA4531 based) on OpenWrt
19.07 we could force a silent restart of a device with no serial
output when we were sending a high amount of UDP traffic (iperf3 at 80
MBit/s in both directions from external hosts, saturating the wifi and
causing a load of about 4.5 to 6) and were then triggering an
ath9k_queue_reset().
Further debugging showed that the restart was caused by the ath79
watchdog. With disabled watchdog we could observe that the device was
constantly going into ath_isr() interrupt handler and was returning
early after the ATH_OP_HW_RESET flag test, without clearing any
interrupts. Even though ath9k_queue_reset() calls
ath9k_hw_kill_interrupts().
With JTAG we could observe the following race condition:
1) ath9k_queue_reset()
...
-> ath9k_hw_kill_interrupts()
-> set_bit(ATH_OP_HW_RESET, &common->op_flags);
...
<- returns
2) ath9k_tasklet()
...
-> ath9k_hw_resume_interrupts()
...
<- returns
3) loops around:
...
handle_int()
-> ath_isr()
...
-> if (test_bit(ATH_OP_HW_RESET,
&common->op_flags))
return IRQ_HANDLED;
x) ath_reset_internal():
=> never reached <=
And in ath_isr() we would typically see the following interrupts /
interrupt causes:
* status: 0x00111030 or 0x00110030
* async_cause: 2 (AR_INTR_MAC_IPQ)
* sync_cause: 0
So the ath9k_tasklet() reenables the ath9k interrupts
through ath9k_hw_resume_interrupts() which ath9k_queue_reset() had just
disabled. And ath_isr() then keeps firing because it returns IRQ_HANDLED
without actually clearing the interrupt.
To fix this IRQ storm also clear/disable the interrupts again when we
are in reset state.

[ Upstream commit e5f5a66c9aa9c331da5527c2e3fd9394e7091e01 ]
Commit c343bf1ba5ef ("cpuidle: Fix three reference count leaks")
fixes the cleanup of kobjects; however, it removes kfree() calls
altogether, leading to memory leaks.
Fix those and also defer the initialization of dev->kobj_dev until
after the error check, so that we do not end up with a dangling
pointer.

[ Upstream commit 7266dda2f1dfe151b12ef0c14eb4d4e622fb211c ]
Currently a call to snd_card_new that fails will set card with a NULL
pointer, this causes a null pointer dereference on the error cleanup
path when card it passed to snd_card_free. Fix this by adding a new
error exit path that does not call snd_card_free and exiting via this
new path.

[ Upstream commit 42bb98e420d454fef3614b70ea11cc59068395f6 ]
The "card" string only holds 31 characters (and the terminating NUL).
In order to avoid truncation, use a shorter card description instead of
the current result, "Trident TVMaster TM5600/6000/60".

'mtk_vpu_probe()'
[ Upstream commit 2143ad413c05c7be24c3a92760e367b7f6aaac92 ]
A successful 'clk_prepare()' call should be balanced by a corresponding
'clk_unprepare()' call in the error handling path of the probe, as already
done in the remove function.
Update the error handling path accordingly.

[ Upstream commit 48d219f9cc667bc6fbc3e3af0b1bfd75db94fce4 ]
Static analysis reports this representative problem
tda1997x.c:1939: warning: 7th function call argument is an uninitialized
value
The 7th argument is buffer[0], which is set in the earlier call to
io_readn(). When io_readn() call to io_read() fails with the first
read, buffer[0] is not set and 0 is returned and stored in len.
The later call to hdmi_infoframe_unpack()'s size parameter is the
static size of buffer, always 40, so a short read is not caught
in hdmi_infoframe_unpacks()'s checking. The variable len should be
used instead.
Zero initialize buffer to 0 so it is in a known start state.

Syzbot reported ununit-value bug in az6027_rc_query(). The problem was
in missing state pointer initialization. Since this function does nothing
we can simply initialize state to REMOTE_NO_KEY_PRESSED.
