[PATCH] efi/riscv: Remove the useless failure return message print

[Qiang Ma]

In the efi_create_mapping() in arch/riscv/kernel/efi.c,
the return value is always 0, and this debug message
is unnecessary. So, remove it.

Should we make efi_create_mapping() return void at the same time, if it
will never fail?

Oops, seems a silly question here. Sorry for the noise.

Considering that Ard doesn't think efi_create_mapping() should be changed 
to remove the return value, and that the ARM version of this code retains 
the debug message, we should probably keep things the way they are.  But 
if you can get a Reviewed-by: or an Acked-by: from Ard, I'd take it.


Thanks for your patch,

- Paul

Hi, Ard, what are your suggestions for this patch?

Could you add a Reviewed-by: or an Acked-by: to this patch?

I already queued this up in efi/next
