Date: Tue, 27 Jun 2017 17:36:36 +0200 From: Arnd Bergmann <arnd@...db.de> To: Olof Johansson <olof@...om.net> Cc: Arnd Bergmann <arnd@...db.de>, Enric Balletbo i Serra <enric.balletbo@...labora.com>, Guenter Roeck <groeck@...omium.org>, Lee Jones <lee.jones@...aro.org>, Jonathan Cameron <jic23@...nel.org>, Benson Leung <bleung@...omium.org>, Eric Caruso <ejcaruso@...omium.org>, Gwendal Grignou <gwendal@...omium.org>, Vincent Palatin <vpalatin@...omium.org>, Jeffery Yu <jefferyy@...dia.com>, Logan Gunthorpe <logang@...tatee.com>, linux-kernel@...r.kernel.org Subject: [PATCH] platform/chrome: cros_ec_lightbar - hide unused PM functions The only reference to the new functions is inside of an #ifdef, which now causes a harmless warning when CONFIG_PM_SLEEP is not set: chrome/cros_ec_dev.c:478:12: error: 'ec_device_resume' defined but not used [-Werror=unused-function] chrome/cros_ec_dev.c:469:12: error: 'ec_device_suspend' defined but not used [-Werror=unused-function] This marks the two functions as __maybe_unused so they can get silently dropped by the compiler.
