[PATCH] binfmt_flat: fix arch/m32r and arch/microblaze flat_put_addr_at_rp()
From: Randy Dunlap
Date: Sun Jul 30 2017 - 13:25:54 EST
From: Randy Dunlap <rdunlap@xxxxxxxxxxxxx>
Change the m32r flat_put_addr_at_rp() function to return int and
always return 0.
The microblaze function already returned 0 so just change its
function return type from void to int.
Seven (7) other arch-es already have this function as returning
an int type result.
Fixes: 468138d78510 (binfmt_flat: flat_{get,put}_addr_from_rp()
should be able to fail)
