From: Bean Huo <beanhuo@micron.com>

Changelog:

V1---v2:
    1. Add new patch "Let resume callback return -EBUSY after ufshcd_shutdown",
       Because the ufshcd_*_resume still returns successful result 0 after
       ufshcd_shutdown(). Even add handling of the return value of
       pm_runtime_get_sync(), but still there is timeout.

Bean Huo (3):
  scsi: ufs: Replace sprintf and snprintf with sysfs_emit
  scsi: ufs: Add handling of the return value of pm_runtime_get_sync()
  scsi: ufs: Let resume callback return -EBUSY after ufshcd_shutdown
