Subject: [PATCH v1] scsi: ufs-mediatek: Enable UFSHCI_QUIRK_SKIP_MANUAL_WB_FLUSH_CTRL
Date:   Tue, 22 Dec 2020 15:29:28 +0800
Message-ID: <20201222072928.32328-1-stanley.chu@mediatek.com>

Precedence: bulk

Flush during hibern8 is sufficient on MediaTek platforms, thus
enable UFSHCI_QUIRK_SKIP_MANUAL_WB_FLUSH_CTRL to skip enabling
fWriteBoosterBufferFlush during WriteBooster initialization.
