[PATCH] [media] media: mtk-mdp: mark PM functions as __maybe_unused Arnd Bergmann <arnd@arndb.de> - 2016-10-26 11:50 +0200

| Subject | [PATCH] [media] media: mtk-mdp: mark PM functions as __maybe_unused |
| Message-ID | <swt0m-1OS-21@gated-at.bofh.it> |
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")
