[PATCH -next] scsi: ufs: ufs-mediatek: Fix build error and type unmatch

From: Ren Zhijie
Date: Sun Jun 19 2022 - 07:56:20 EST


If CONFIG_PM_SLEEP is not set.

make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu-, will be failed, like this:

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);
~^ ~~~~~~

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]

drivers/ufs/host/ufs-mediatek.c: In function ‘ufs_mtk_system_resume’:
drivers/ufs/host/ufs-mediatek.c:1386:9: error: implicit declaration of function ‘ufshcd_system_resume’; did you mean ‘ufs_mtk_system_resume’? [-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()" is depended on CONFIG_PM_SLEEP, so the function wrapper "ufs_mtk_system_suspend()" should warpped by CONFIG_PM_SLEEP too.
