From af2e14bb3f6cbe67459f17dd2879bb475a9c4e09 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Thu, 30 Jun 2016 09:23:02 -0300 Subject: [PATCH] [media] vsp1: use __maybe_unused for PM handlers Building without CONFIG_PM results in a harmless warning from slightly incorrect #ifdef guards: drivers/media/platform/vsp1/vsp1_drv.c:525:12: error: 'vsp1_pm_runtime_resume' defined but not used [-Werror=unused-function] drivers/media/platform/vsp1/vsp1_drv.c:516:12: error: 'vsp1_pm_runtime_suspend' defined but not used [-Werror=unused-function] This removes the existing #ifdef and instead marks all four PM functions as __maybe_unused.
