[ Upstream commit 81f8c0e138c43610cf09b8d2a533068aa58e538e ]
The Sonix Technology Co. 292A camera (which uses an AR0330 sensor), can produce MJPEG and H.264 streams concurrently. When doing so, it drops the last packets of MJPEG frames every time the H.264 stream generates a key frame. Set the UVC_QUIRK_MJPEG_NO_EOF quirk to work around the issue.
