commit 085fc31f81765e061c78cdcab0e5516fd672bff7 upstream.
360 degree hinges devices with dual KIOX010A + KIOX020A accelerometers
always have both a KIOX010A and a KIOX020A ACPI device (one for each
accel).
Theoretical some vendor may re-use some DSDT for a non-convertible
stripping out just the KIOX020A ACPI device from the DSDT. Check that
both ACPI devices are present to make the check more robust.

commit c7e9d0020361f4308a70cdfd6d5335e273eb8717 upstream.
The patch breaks userspace implementations (e.g. fdutils) and introduces
regressions in behaviour. Previously, it was possible to O_NDELAY open a
floppy device with no media inserted or with write protected media without
an error. Some userspace tools use this particular behavior for probing.
It's not the first time when we revert this patch. Previous revert is in
commit f2791e7eadf4 (Revert "floppy: refactor open() flags handling").
This reverts commit 8a0c014cd20516ade9654fc13b51345ec58e7be8.

commit 7428022b50d0fbb4846dd0f00639ea09d36dff02 upstream.
When a port leaves a VLAN-aware bridge, the current code does not clear
other ports' matrix field bit. If the bridge is later set to VLAN-unaware
mode, traffic in the bridge may leak to that port.
Remove the VLAN filtering check in mt7530_port_bridge_leave.

commit 55981d3541812234e687062926ff199c83f79a39 upstream.
Some USB BT adapters don't satisfy the MTU requirement mentioned in
commit e848dbd364ac ("Bluetooth: btusb: Add support USB ALT 3 for WBS")
and have ALT 3 setting that produces no/garbled audio. Some adapters
with larger MTU were also reported to have problems with ALT 3.
Add a flag and check it and MTU before selecting ALT 3, falling back to
ALT 1. Enable the flag for Realtek, restoring the previous behavior for
non-Realtek devices.
Tested with USB adapters (mtu<72, no/garbled sound with ALT3, ALT1
works) BCM20702A1 0b05:17cb, CSR8510A10 0a12:0001, and (mtu>=72, ALT3
works) RTL8761BU 0bda:8771, Intel AX200 8087:0029 (after disabling
ALT6). Also got reports for (mtu>=72, ALT 3 reported to produce bad
audio) Intel 8087:0a2b.

[ Upstream commit 6eaa1f3c59a707332e921e32782ffcad49915c5e ]
When booted with multiple displays attached, the EFI GOP driver on (at
least) Ampere, can leave DP links powered up that aren't being used to
display anything. This confuses our tracking of SOR routing, with the
likely result being a failed modeset and display engine hang.
Fix this by (ab?)using the DisableLT IED script to power-down the link,
restoring HW to a state the driver expects.

[ Upstream commit fa0b1ef5f7a694f48e00804a391245f3471aa155 ]
[Why]
Userspace should get back a copy of drm_wait_vblank that's been modified
even when drm_wait_vblank_ioctl returns a failure.
Rationale:
drm_wait_vblank_ioctl modifies the request and expects the user to read
it back. When the type is RELATIVE, it modifies it to ABSOLUTE and updates
the sequence to become current_vblank_count + sequence (which was
RELATIVE), but now it became ABSOLUTE.
drmWaitVBlank (in libdrm) expects this to be the case as it modifies
the request to be Absolute so it expects the sequence to would have been
updated.
The change is in compat_drm_wait_vblank, which is called by
drm_compat_ioctl. This change of copying the data back regardless of the
return number makes it en par with drm_ioctl, which always copies the
data before returning.
[How]
Return from the function after everything has been copied to user.

[ Upstream commit e74cfa91f42c50f7f649b0eca46aa049754ccdbd ]
As __vringh_iov() traverses a descriptor chain, it populates
each descriptor entry into either read or write vring iov
and increments that iov's ->used member. So, as we iterate
over a descriptor chain, at any point, (riov/wriov)->used
value gives the number of descriptor enteries available,
which are to be read or written by the device. As all read
iovs must precede the write iovs, wiov->used should be zero
when we are traversing a read descriptor. Current code checks
for wiov->i, to figure out whether any previous entry in the
current descriptor chain was a write descriptor. However,
iov->i is only incremented, when these vring iovs are consumed,
at a later point, and remain 0 in __vringh_iov(). So, correct
the check for read and write descriptor order, to use
wiov->used.

[ Upstream commit 60f0779862e4ab943810187752c462e85f5fa371 ]
Currently vq->broken field is read by virtqueue_is_broken() in busy
loop in one context by virtnet_send_command().
vq->broken is set to true in other process context by
virtio_break_device(). Reader and writer are accessing it without any
synchronization. This may lead to a compiler optimization which may
result to optimize reading vq->broken only once.
Hence, force reading vq->broken on each invocation of
virtqueue_is_broken() and also force writing it so that such
update is visible to the readers.
It is a theoretical fix that isn't yet encountered in the field.

[ Upstream commit 885814a97f5a1a2daf66bde5f2076f0bf632c174 ]
This reverts commit 419dd626e357e89fc9c4e3863592c8b38cfe1571.
It turned out that the change from the reverted commit breaks the ACPI
based rpi's because it causes the 100Mhz max clock to be overridden to the
return from sdhci_iproc_get_max_clock(), which is 0 because there isn't a
OF/DT based clock device.

The commit 71f642833284 ("ACPI: utils: Fix reference counting in
for_each_acpi_dev_match()") moved adev assignment outside of error
path and hence made acpi_dev_put(sensor->adev) a no-op. We still
need to drop reference count on error path, and to achieve that,
replace sensor->adev by locally assigned adev.

[ Upstream commit 8c1671e0d13d4a0ba4fb3a0da932bf3736d7ff73 ]
Currently, when query PFC configuration by dcbtool, driver will return
PFC enable status based on TC. As all priorities are mapped to TC0 by
default, if TC0 is enabled, then all priorities mapped to TC0 will be
shown as enabled status when query PFC setting, even though some
priorities have never been set.
for example:
$ dcb pfc show dev eth0
pfc-cap 4 macsec-bypass off delay 0
prio-pfc 0:off 1:off 2:off 3:off 4:off 5:off 6:off 7:off
$ dcb pfc set dev eth0 prio-pfc 0:on 1:on 2:on 3:on
$ dcb pfc show dev eth0
pfc-cap 4 macsec-bypass off delay 0
prio-pfc 0:on 1:on 2:on 3:on 4:on 5:on 6:on 7:on
To fix this problem, just returns user's PFC config parameter saved in
driver.

In bond 4, when the link goes down and up repeatedly, the bond may get an
unknown speed, and then this port can not work.
The driver notify netif_carrier_on() before update the link state, when the

operation happens before updating the link state, will get an unknown
speed. So need to notify netif_carrier_on() after update the link state.

[ Upstream commit b7658ed35a5f5900f0f658e375f366513f3eb781 ]
Traffic schedules can only be started up to eight seconds within the
future. Therefore, the driver periodically checks every two seconds whether the
admin base time provided by the user is inside that window. If so the schedule
is started. Otherwise the check is deferred.
However, according to the programming manual the look ahead window size should
be four - not eight - seconds. By using the proposed value of four seconds
starting a schedule at a specified admin base time actually works as expected.

The devlink dev info command reports version information about the
device and firmware running on the board. This includes the "board.id"
field which is supposed to represent an identifier of the board design.
The ice driver uses the Product Board Assembly identifier for this.
In some cases, the PBA is not present in the NVM. If this happens,
devlink dev info will fail with an error. Instead, modify the
ice_info_pba function to just exit without filling in the context
buffer. This will cause the board.id field to be skipped. Log a dev_dbg
message in case someone wants to confirm why board.id is not showing up
for them.
