The module param `nodrop` defines what to do with frames that contain an error: drop them or sending them to userspace. The default in the rest of the media subsystem is to return buffers with an error to userspace with V4L2_BUF_FLAG_ERROR set in v4l2_buffer.flags. In UVC we drop buffers with errors by default. Change the default behaviour of uvcvideo to match the rest of the drivers and maybe get rid of the module parameter in the future.
