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.

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.

V4L2_PIX_FMT_Y16IInterlaced lumina format primary use in RealSense Depth cameras with stereo stream for left and right image sensors.
This will add unneeded defines to -stable.
