Subject: m32r: fix 'fix breakage from "m32r: use generic ptrace_resume code"' fallout
acdc0d5ef9dd ('m32r: fix breakage from "m32r: use generic ptrace_resume
code"') tried to fix 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.
