Subject: [PATCH] [media] media: mtk-mdp: mark PM functions as __maybe_unused
Date: Wed, 26 Oct 2016 11:43:43 +0200 [thread overview]
Message-ID: <20161026094411.785911-1-arnd@arndb.de> (raw)
A previous patch tried to fix a build error, but introduced another
warning:
drivers/media/platform/mtk-mdp/mtk_mdp_core.c:71:13: error: ?mtk_mdp_clock_off? defined but not used [-Werror=unused-function]
drivers/media/platform/mtk-mdp/mtk_mdp_core.c:62:13: error: ?mtk_mdp_clock_on? defined but not used [-Werror=unused-function]
This marks all the PM functions as __maybe_unused and removes
the #ifdef around them, as that will always do the right thing.
Fixes: 1b06fcf56aa6 ("[media] media: mtk-mdp: fix build error")
