From 5992a7910b1f6f245cbcf173b31ba9169ad31649 Mon Sep 17 00:00:00 2001 From: Ren Zhijie Date: Sun, 19 Jun 2022 19:54:32 +0800 Subject: [PATCH] scsi: ufs: ufs-mediatek: Fix build error and type mismatch MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit BugLink: https://bugs.launchpad.net/bugs/1990564 commit f54912b228a8df6c0133e31bc75628677bb8c6e5 upstream. If CONFIG_PM_SLEEP is not set. make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu-, will fail: drivers/ufs/host/ufs-mediatek.c: In function ‘ufs_mtk_vreg_fix_vcc’: drivers/ufs/host/ufs-mediatek.c:688:46: warning: format ‘%u’ expects argument of type ‘unsigned int’, but argument 4 has type ‘long unsigned int’ [-Wformat=] snprintf(vcc_name, MAX_VCC_NAME, "vcc-opt%u", res.a1); ~^ ~~~~~~ %lu drivers/ufs/host/ufs-mediatek.c: In function ‘ufs_mtk_system_suspend’: drivers/ufs/host/ufs-mediatek.c:1371:8: error: implicit declaration of function ‘ufshcd_system_suspend’; did you mean ‘ufs_mtk_system_suspend’?

[-Werror=implicit-function-declaration] return ufshcd_system_resume(dev); ^~~~~~~~~~~~~~~~~~~~ ufs_mtk_system_resume cc1: some warnings being treated as errors The declaration of func "ufshcd_system_suspend()" depends on CONFIG_PM_SLEEP, so the function wrapper ufs_mtk_system_suspend() should wrapped by CONFIG_PM_SLEEP too.
