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
