From: Arnd Bergmann Date: Wed, 2 Mar 2016 17:11:16 +0000 (-0800) Subject: Input: spear-keyboard - use __maybe_unused to hide pm functions X-Git-Tag: next-20160307~60^2~7 X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=7ffae9909bddb0367052133fe74ec5c9898c27b4;p=karo-tx-linux.git Input: spear-keyboard - use __maybe_unused to hide pm functions The spear keyboard driver uses #ifdef CONFIG_PM to hide its power management functions, but then uses references from SIMPLE_DEV_PM_OPS that are only present if both CONFIG_PM and CONFIG_PM_SLEEP are set, resulting in a warning about unused functions: drivers/input/keyboard/spear-keyboard.c:292:12: error: 'spear_kbd_suspend' defined but not used [-Werror=unused-function] drivers/input/keyboard/spear-keyboard.c:345:12: error: 'spear_kbd_resume' defined but not used [-Werror=unused-function] This removes the #ifdef and instead uses a __maybe_unused annotation.
