From 5bc55ef31f710326f541e6a3c726526815dd48e6 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Fri, 26 Aug 2016 17:31:19 +0200 Subject: [PATCH] iio: magn/ak8974: avoid unused function warning The ak8974_configure() function is used only from the PM code, but that can be hidden when CONFIG_PM is disabled: drivers/iio/magnetometer/ak8974.c:201:12: error: 'ak8974_configure' defined but not used [-Werror=unused-function] This replaces the #ifdef with a __maybe_unused annotation, which will work correctly in all configurations and avoid the warning, as the compiler can now see where ak8974_configure is called from.
