Asutosh Das tried to upstream this change about a year ago.
We would like to resume his work because Qualcomm's ufs controller
needs to be in hibern8 before scaling up/down the clocks.
Just like ufshcd_uic_hibern8_exit() is already being exported,
we would like to export ufshcd_uic_hibern8_enter() so that
Qualcomm's ufs controller can be put in hibern8 state.

Asutosh Das (2):
  scsi: ufs: export hibern8 entry and exit
  scsi: ufs-qcom: enter and exit hibern8 during clock scaling
