From: Arnd Bergmann Date: Thu, 19 Oct 2017 09:30:34 +0000 (-0400) Subject: media: rockchip/rga: annotate PM functions as __maybe_unused X-Git-Tag: v4.19~2007^2~128 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=94b28441c9c7168bfdef932703f968a43ba77f97;p=platform%2Fkernel%2Flinux-rpi.git media: rockchip/rga: annotate PM functions as __maybe_unused The newly added driver has incorrect #ifdef annotations on its PM functions, leading to a harmless compile-time warning when CONFIG_PM is disabled: drivers/media/platform/rockchip/rga/rga.c:760:13: error: 'rga_disable_clocks' defined but not used [-Werror=unused-function] static void rga_disable_clocks(struct rockchip_rga *rga) ^~~~~~~~~~~~~~~~~~ drivers/media/platform/rockchip/rga/rga.c:728:12: error: 'rga_enable_clocks' defined but not used [-Werror=unused-function] This removes the #ifdef and marks the functions as __maybe_unused, so gcc can silently drop all the unused code.
