Subject: [PATCH v2] scsi: ufs: Guard the ufs_mtk_runtime_suspend and ufs_mtk_runtime_resume with CONFIG_PM
From: Shida Zhang <zhangshida@...inos.cn>
In a configuration with CONFIG_SCSI_UFS_MEDIATEK set to 'm' and
CONFIG_PM set to 'n', errors occur at compile time:
====
../drivers/ufs/host/ufs-mediatek.c: In function ‘ufs_mtk_runtime_suspend’:
../drivers/ufs/host/ufs-mediatek.c:1621:8: error: implicit declaration of function ‘ufshcd_runtime_suspend’; did you mean ‘ufs_mtk_runtime_suspend’? [-Werror=implicit-function-declaration]
../drivers/ufs/host/ufs-mediatek.c: In function ‘ufs_mtk_runtime_resume’:
../drivers/ufs/host/ufs-mediatek.c:1636:9: error: implicit declaration of function ‘ufshcd_runtime_resume’; did you mean ‘ufs_mtk_runtime_resume’? [-Werror=implicit-function-declaration]
====
This patch fixes these by guarding these functions with CONFIG_PM.

Changes in v2:
Guarding these functions with CONFIG_PM instead of selecting the config.
