Hi Alaa, FYI: this patch has already been applied to the media_tree master git repo: https://patchwork.linuxtv.org/project/linux-media/patch/2c46832a-99a8-73bf-ec85-085052f8b4db@xxxxxxxxx/ That's good enough for this issue so I am marking this patch as Obsolete in our patchwork.

Make sure you configure your editor not to do that. Regards, Hans > return -EIO; > } > return 0; >
