arc: ptrace: user_regset_copyin_ignore() always returns 0
Patch series "Make user_regset_copyin_ignore() *void*".
user_regset_copyin_ignore() apparently cannot fail and so always returns 0.
Let's first remove the result checks in several architectures that call this
function and then make user_regset_copyin_ignore() return *void* instead of
*int*...
This patch (of 13):
user_regset_copyin_ignore() always returns 0, so checking its result seems
pointless -- don't do this anymore...
