Subject[PATCH 1/2] x86: apm: mark proc_apm_show as __maybe_unused
Date
A new build error appeared with CONFIG_PROC_FS disabled:

arch/x86/kernel/apm_32.c:1643:12: error: 'proc_apm_show' defined but not used [-Werror=unused-function]

This marks the function as __maybe_unused to let the compiler drop
it silently.

Fixes: 3f3942aca6da ("proc: introduce proc_create_single{,_data}")
Signed-off-by: Arnd Bergmann <arnd@arndb.de>
