[PATCH] media: camss: mark PM functions as __maybe_unused

From: Arnd Bergmann
Date: Fri Aug 17 2018 - 05:54:36 EST


The empty suspend/resume functions cause a build warning
when they are unused:

drivers/media/platform/qcom/camss/camss.c:1001:12: error: 'camss_runtime_resume' defined but not used [-Werror=unused-function]
drivers/media/platform/qcom/camss/camss.c:996:12: error: 'camss_runtime_suspend' defined but not used [-Werror=unused-function]

Mark them as __maybe_unused so the compiler can silently drop them.

Fixes: 02afa816dbbf ("media: camss: Add basic runtime PM support")
