commit 018d4671b9bbd4a5c55cf6eab3e1dbc70a50b66e upstream.
On failing to prepare or enable a clock, remove the core structure
from the list it has been inserted as it is about to be freed.
This otherwise leads to random crashes when subsequent clocks get
registered, during which parsing of the clock tree becomes adventurous.
Observed with QEMU's RPi-3 emulation.

commit 00e21763f2c8cab21b7befa52996d1b18bde5c42 upstream.
The check for the HWO flag in dwc3_gadget_ep_reclaim_trb_sg()
causes us to break out of the loop before we call
dwc3_gadget_ep_reclaim_completed_trb(), which is what likely
should be clearing the HWO flag.
This can cause odd behavior where we never reclaim all the trbs
in the sg list, so we never call giveback on a usb req, and that
will causes transfer stalls.
This effectively resovles the adb stalls seen on HiKey960
after userland changes started only using AIO in adbd.

commit cec9d101d70a3509da9bd2e601e0b242154ce616 upstream.
The following changes prevent the unrecoverable freezes and rcu_sched
stall warnings experienced in each of my attempts to take advantage of
lima.
Replace the COMPOSITE_NOGATE definition of aclk_gpu_pre with a
COMPOSITE that retains the selection of HDMIPHY as the PLL source, but
instead makes uses of the aclk_gpu PLL source gate and parent names
defined by mux_pll_src_4plls_p rather than mux_aclk_gpu_pre_p.
Remove the now unused mux_aclk_gpu_pre_p and the four named but also
unused definitions (cpll_gpu, gpll_gpu, hdmiphy_gpu and usb480m_gpu)
of the aclk_gpu PLL source gate.
Use the correct gate offset for aclk_gpu and aclk_gpu_noc.

commit 3c6f8cb92c9178fc0c66b580ea3df1fa3ac1155a upstream.
On platforms with IOMMU enabled, multiple SGs can be coalesced into one
by the IOMMU driver. In that case the SG list processing as part of the
completion of a urb on a bulk endpoint can result into a NULL pointer
dereference with the below stack dump.

The above NULL pointer dereference is the result of block_len and the
sent_len set to zero after the first SG of the list when IOMMU driver
is enabled. Because of this the loop of processing the SGs has run
more than num_sgs which resulted in a sg_next on the last SG of the
list which has SG_END set.
Fix this by check for the sg before any attributes of the sg are
accessed.

commit 15753588bcd4bbffae1cca33c8ced5722477fe1f upstream.
FuzzUSB (a variant of syzkaller) found an illegal array access
using an incorrect index while binding a gadget with UDC.
Reference: https://www.spinics.net/lists/linux-usb/msg194331.html
This bug occurs when a size variable used for a buffer
is misused to access its strcpy-ed buffer.
Given a buffer along with its size variable (taken from user input),
from which, a new buffer is created using kstrdup().
Due to the original buffer containing 0 value in the middle,
the size of the kstrdup-ed buffer becomes smaller than that of the original.
So accessing the kstrdup-ed buffer with the same size variable
triggers memory access violation.
The fix makes sure no zero value in the buffer,
by comparing the strlen() of the orignal buffer with the size variable,
so that the access to the kstrdup-ed buffer is safe.

commit 1449cb2c2253d37d998c3714aa9b95416d16d379 upstream.
While removing the host (e.g. for USB role switch from host to device),
if runtime pm is enabled by user, below oops occurs on dwc3 and cdns3
platforms.
Keeping the xhci-plat device active during host removal, and disabling
runtime pm before calling pm_runtime_set_suspended() fixes them.

commit 76e1ef1d81a4129d7e2fb8c48c83b166d1c8e040 upstream.

> This patch prevents my Raven Ridge xHCI from getting runtime suspend.
The problem described in v5.6 commit 1208f9e1d758c9 ("USB: hub: Fix the
broken detection of USB3 device in SMSC hub") applies solely to the
USB5534B hub [2] present on the Kingfisher Infotainment Carrier Board,
manufactured by Shimafuji Electric Inc [3].
Despite that, the aforementioned commit applied the quirk to _all_ hubs
carrying vendor ID 0x424 (i.e. SMSC), of which there are more [4] than
initially expected. Consequently, the quirk is now enabled on platforms
carrying SMSC/Microchip hub models which potentially don't exhibit the
original issue.
To avoid reports like [1], further limit the quirk's scope to
USB5534B [2], by employing both Vendor and Product ID checks.
Tested on H3ULCB + Kingfisher rev. M05.

[ Upstream commit 333e22db228f0bd0c839553015a6a8d3db4ba569 ]
When tsi-as-adc is configured it is possible for in7[0123]_input read to
return an incorrect value if a concurrent read to in[456]_input is
performed. This is caused by a concurrent manipulation of the mux
channel without proper locking as hwmon and mfd use different locks for
synchronization.
Switch hwmon to use the same lock as mfd when accessing the TSI channel.

[ Upstream commit c077dc5e0620508a29497dac63a2822324ece52a ]
First, it should be noted that the CQE timeout (60 seconds) is substantial
so a CQE request that times out is really stuck, and the race between
timeout and completion is extremely unlikely. Nevertheless this patch
fixes an issue with it.
Commit ad73d6feadbd7b ("mmc: complete requests from ->timeout")
preserved the existing functionality, to complete the request.
However that had only been necessary because the block layer
timeout handler had been marking the request to prevent it from being
completed normally. That restriction was removed at the same time, the
result being that a request that has gone will have been completed anyway.
That is, the completion was unnecessary.
At the time, the unnecessary completion was harmless because the block
layer would ignore it, although that changed in kernel v5.0.
Note for stable, this patch will not apply cleanly without patch "mmc:
core: Fix recursive locking issue in CQE recovery path"

[ Upstream commit e6bfb1bf00852b55f4c771f47ae67004c04d3c87 ]
In the request completion path with CQE, request type is being checked
after the request is getting completed. This is resulting in returning
the wrong request type and leading to the IO hang issue.
ASYNC request type is getting returned for DCMD type requests.
Because of this mismatch, mq->cqe_busy flag is never getting cleared
and the driver is not invoking blk_mq_hw_run_queue. So requests are not
getting dispatched to the LLD from the block layer.
All these eventually leading to IO hang issues.
So, get the request type before completing the request.

[ Upstream commit 01c3259818a11f3cc3cd767adbae6b45849c03c1 ]
When we fill up a receive VQ, try_fill_recv currently tries to count
kicks using a 64 bit stats counter. Turns out, on a 32 bit kernel that
uses a seqcount. sequence counts are "lock" constructs where you need to
make sure that writers are serialized.
In turn, this means that we mustn't run two try_fill_recv concurrently.
Which of course we don't. We do run try_fill_recv sometimes from a
softirq napi context, and sometimes from a fully preemptible context,
but the later always runs with napi disabled.
However, when it comes to the seqcount, lockdep is trying to enforce the
rule that the same lock isn't accessed from preemptible and softirq
context - it doesn't know about napi being enabled/disabled. This causes
a false-positive warning:
WARNING: inconsistent lock state
...
inconsistent {SOFTIRQ-ON-W} -> {IN-SOFTIRQ-W} usage.
As a work around, shut down the warning by switching
to u64_stats_update_begin_irqsave - that works by disabling
interrupts on 32 bit only, is a NOP on 64 bit.

A related problem is that virtblk_remove() leaks the vd_index_ida index

Fix these issues by protecting vblk->vdev with a mutex and reference
counting vblk so the vd_index_ida index can be removed in all cases.
