Subject: media: camss: mark PM functions as __maybe_unused
X-Git-Tag: v4.19~105^2~6
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=44a9ffd4eb99ada6c1496a735a414414fef30696;p=platform%2Fkernel%2Flinux-rpi.git

media: camss: mark PM functions as __maybe_unused

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")
