    Subject[PATCH v1 08/17] scsi: ufs: split broken LCC quirk
    Date
    Currently when UFSHCD_BROKEN_LCC quirk is defined, LCC is getting
    disabled on both host and device side but there could be a need
    where we don't want to disable the LCC on both side hence this change
    splits the quirk in 2 parts one for host and one for device.
