[PATCH] EFI booting may hang indefinitely when no keyboard is present
...to not init USB due to fast boot).
Reproducible at least with "EFI v2.31 by American Megatrends" on an
Asrock H81M-ITX board.
Reason is the input draining loop near the end in efi/main.c; it calls
ReadKeyStroke() as long as EFI_NOT_READY is not returned. On machines
without keyboard, EFI_DEVICE_ERROR may be returned instead, causing
infinite looping. Positively checking for EFI_SUCCESS keeps the intent
while avoiding this behavior.
Patch is against 6.03; the issue is still present in 6.04 as per
