Size: Stepwise 0x0 - 0x0 with step 0/0 Before this change, the driver would return EINVAL, which is also invalid but worked in GStreamer. The original intent was not to implement it, hence the -ENOTTY return in this change. While drivers should implement ENUM_FRMSIZE for all formats and queues, this change is limited in scope to fix the regression. This fixes taking picture in Gnome Cheese software, or any software using GSteamer to encode JPEG with hardware acceleration.
