+Description
+===========
+
+This is a grey-scale image with a depth of 16 bits per pixel, but with pixels
+from 2 sources interleaved and unpacked. Each pixel is stored in a 16-bit word
+in the little-endian order. The first pixel is from the left source.
+
+**Pixel unpacked representation.**
+Left/Right pixels 16-bit unpacked - 16-bit for each interleaved pixel.

[ Upstream commit 88785982a19daa765e30ab3a605680202cfaee4e ]
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).

[ Upstream commit 61a830bc0ea69a05d8a4534f825c6aa618263649 ]
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.
