Date: Wed, 2 Mar 2016 16:58:57 +0100 From: Arnd Bergmann <arnd@...db.de> To: Lee Jones <lee.jones@...aro.org> Cc: linux-arm-kernel@...ts.infradead.org, Arnd Bergmann <arnd@...db.de>, linux-kernel@...r.kernel.org Subject: [PATCH 05/14] mfd: ipaq-micro: use __maybe_unused to hide pm functions The ipaq-micro driver uses SET_SYSTEM_SLEEP_PM_OPS() to remove the reference to its resume function, but does not use an #ifdef around the definition, so we get a build warning: drivers/mfd/ipaq-micro.c:379:12: error: 'micro_resume' defined but not used [-Werror=unused-function] This adds a __maybe_unused annotation so the compiler knows it can silently drop it instead of warning.
