3.2.100-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Geert Uytterhoeven <geert@xxxxxxxxxxxxxx>
commit a6b202979661eb32646048aeaad7be7b70c2cd22 upstream.
Commit acdc0d5ef9dd ('m32r: fix breakage from "m32r: use generic
ptrace_resume code"') tried to fix a problem in commit e34112e3966fc
("m32r: use generic ptrace_resume code") by returning values in a
function returning void, causing:
arch/m32r/kernel/ptrace.c: In function 'user_enable_single_step':
arch/m32r/kernel/ptrace.c:594:3: warning: 'return' with a value, in function returning void [enabled by default]
arch/m32r/kernel/ptrace.c:598:3: warning: 'return' with a value, in function returning void [enabled by default]
arch/m32r/kernel/ptrace.c:601:3: warning: 'return' with a value, in function returning void [enabled by default]
arch/m32r/kernel/ptrace.c:604:2: warning: 'return' with a value, in function returning void [enabled by default]
Remove the unneeded return values.
