Sergey Shtylyov 461cc6e54e 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...
