Subject: [PATCH v2 3/3] ufs-qcom: scsi: configure write booster type

Configure the WriteBooster type to preserve user-space mode.
This would ensure that no user-space capacity is reduced
when write booster is enabled.
Enable WB for Qualcomm platform.

The above does no longer apply - leftover from previous patch?

Thanks,
