Subject: [PATCH 0/3] media: uvcvideo: Support partial control reads and minor changes
Date: Tue, 08 Oct 2024 07:06:13 +0000 [thread overview]
Message-ID: <20241008-uvc-readless-v1-0-042ac4581f44@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().
