Subject: [PATCH] video/efi_gop: Remove unnecessary return value of
grub_video_gop_fill_mode_info()
The return value of grub_video_gop_fill_mode_info() is never able to be
anything other than GRUB_ERR_NONE. So, rather than continue to return
a value and checking it each time, it is more correct to redefine the
function to not return anything and remove checks of its return value
altogether.
Fixes: CID 96701
