From 46ec9592ffd679fa26142dcb9e5119aad7e60b55 Mon Sep 17 00:00:00 2001 From: Stanley Chu <stanley.chu@mediatek.com> Date: Tue, 22 Dec 2020 15:29:28 +0800 Subject: [PATCH] scsi: ufs-mediatek: Enable UFSHCI_QUIRK_SKIP_MANUAL_WB_FLUSH_CTRL Flush during hibern8 is sufficient on MediaTek platforms, thus enable UFSHCI_QUIRK_SKIP_MANUAL_WB_FLUSH_CTRL to skip enabling fWriteBoosterBufferFlush during WriteBooster initialization.
