If the wait_prepare or wait_finish callback is set, then call it. If it is NULL and the queue lock pointer is not NULL, then just unlock/lock that mutex.
This allows simplifying drivers by dropping the wait_prepare and wait_finish ops (and eventually the vb2_ops_wait_prepare/finish helpers).

Add Dexatek Technology Ltd USB Video Grabber 1d19:6108 to the cx231xx driver. This device is sold under the name "BAUHN DVD Maker (DK8723)" by ALDI in Australia.
This device is similar to 1d19:6109, which is already included in cx231xx.
Both video and audio capture function correctly after installing the patched cx231xx driver.
Patch Changelog v1: - Initial submission. v2: - Fix SoB + Improve subject. v3: - Rephrase message to not exceed 75 characters per line. - Removed reference to external GitHub URL.

[ Upstream commit 9cc832d37799dbea950c4c8a34721b02b8b5a8ff ]
With driver_async_probe=* on kernel command line, the following trace is produced because on i.MX8M Plus hardware because the soc-imx8m.c driver calls of_clk_get_by_name() which returns -EPROBE_DEFER because the clock driver is not yet probed. This was not detected during regular testing without driver_async_probe.
Convert the SoC code to platform driver and instantiate a platform device in its current device_initcall() to probe the platform driver. Rework .soc_revision callback to always return valid error code and return SoC revision via parameter. This way, if anything in the .soc_revision callback return -EPROBE_DEFER, it gets propagated to .probe and the .probe will get retried later.

[ Upstream commit 9bc089307e8dff7797233308372b4a90ce8f79be ]
Mistel MD770 keyboard (using Holtek Semiconductor, Inc. controller) has a quirk in report descriptor in one of its interfaces (more detail in the source file). Fix up the descriptor to allow NKRO to work again.
Tested by loading the BPF program and confirming that 8 simultaneous keypresses work.

[ Upstream commit 62d2a940f29e6aa5a1d844a90820ca6240a99b34 ]
Avoid using GPIOF_ACTIVE_LOW as it's deprecated and subject to remove.
