This patch refers to the UVC_QUIRK_MJPEG_NO_EOF quirk. The series can be viewed at: https://lore.kernel.org/all/20241128145144.61475-1-isaac.scott@xxxxxxxxxxxxxxxx/ In use cases where a camera needs to use the UVC_QUIRK_MJPEG_NO_EOF, erroneous frames that do not conform to MJPEG standards are correctly being marked as erroneous. However, if this happens, we should avoid losing a whole frame of data by enabling the uvc_no_drop parameter. Only the buffer containing the EOF is lost, so it does not make sense to drop the entirety of an otherwise correct buffer just because of this issue. The frame should be marked as erroneous, but the otherwise correct frame should be passed to user space. To do this, you would have to enable the uvc_no_drop parameter. To avoid the extra steps needed to configure the kernel in such a way, enable the no_drop parameter by default to comply with this use case.
