Subject: [PATCH] drm/msm: mark PM functions as __maybe_unused
Date: Tue, 24 Jul 2018 17:35:37 +0200 [thread overview]
Message-ID: <20180724153604.2811956-1-arnd@arndb.de> (raw)
The suspend/resume functions are not referenced when power
management is disabled:
drivers/gpu/drm/msm/disp/dpu1/dpu_kms.c:1288:12: error: 'dpu_runtime_resume' defined but not used [-Werror=unused-function]
drivers/gpu/drm/msm/disp/dpu1/dpu_kms.c:1261:12: error: 'dpu_runtime_suspend' defined but not used [-Werror=unused-function]
This marks them as __maybe_unused to let the compiler
drop the functions without complaining.
Fixes: 591225291ca2 ("drm/msm: Add SDM845 DPU support")
