Subject: [PATCH v2 0/2] media: uvcvideo: Support partial control reads and minor changes
Date: Tue, 08 Oct 2024 15:00:06 +0000 [thread overview]
Message-ID: <20241008-uvc-readless-v2-0-04d9d51aee56@chromium.org> (raw)
Some cameras do not return all the bytes requested from a control
if it can fit in less bytes. Eg: returning 0xab instead of 0x00ab.
Support these devices.
Also, now that we are at it, improve uvc_query_ctrl() logging.
Signed-off-by: Ricardo Ribalda <ribalda@chromium.org>

Changes in v2:
- Rewrite error handling (Thanks Sakari)
- Discard 2/3. It is not needed after rewriting the error handling.
- Link to v1: https://lore.kernel.org/r/20241008-uvc-readless-v1-0-042ac4581f44@chromium.org
