From 51d979c0bb99cb82d597795439eb5d74d280df50 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Mon, 20 Mar 2017 06:47:55 -0300 Subject: [PATCH] [media] vcodec: mediatek: mark pm functions as __maybe_unused When CONFIG_PM is disabled, we get a couple of unused functions: drivers/media/platform/mtk-jpeg/mtk_jpeg_core.c:927:13: error: 'mtk_jpeg_clk_off' defined but not used [-Werror=unused-function] static void mtk_jpeg_clk_off(struct mtk_jpeg_dev *jpeg) ^~~~~~~~~~~~~~~~ drivers/media/platform/mtk-jpeg/mtk_jpeg_core.c:916:13: error: 'mtk_jpeg_clk_on' defined but not used [-Werror=unused-function] static void mtk_jpeg_clk_on(struct mtk_jpeg_dev *jpeg) Rather than adding more error-prone #ifdefs around those, this patch removes the existing #ifdef checks and marks the PM functions as __maybe_unused to let gcc do the right thing.
