That function applies the auto-hibernation settings by writing hba->ahit into the auto-hibernation control register. Simplify the code for disabling auto-hibernation by setting hba->ahit instead of writing into the auto-hibernation control register. This patch is part of an effort to move all auto-hibernation register changes into the UFSHCI driver core. Reviewed-by: Bao D. Nguyen Cc: Martin K.
