From 990c10091db318c7eb7e8935c86b6f7c01585015 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Fri, 6 Jul 2018 09:47:51 -0700 Subject: [PATCH] soc: ti: wkup_m3_ipc: mark PM functions as __maybe_unused Everyone gets these #ifdefs wrong, leading to another warning here: drivers/soc/ti/wkup_m3_ipc.c:547:12: error: 'wkup_m3_ipc_resume' defined but not used [-Werror=unused-function] static int wkup_m3_ipc_resume(struct device *dev) drivers/soc/ti/wkup_m3_ipc.c:539:12: error: 'wkup_m3_ipc_suspend' defined but not used [-Werror=unused-function] static int wkup_m3_ipc_suspend(struct device *dev) The easiest way to get it right is to remove all the #ifdefs and let the compiler drop the unused functions silently after we mark them as __maybe_unused.
