Subject: [PATCH v2 2/2] scsi: ufs: Relax the condition of UFSHCI_QUIRK_SKIP_MANUAL_WB_FLUSH_CTRL
Date:   Tue, 22 Dec 2020 15:29:05 +0800

UFSHCI_QUIRK_SKIP_MANUAL_WB_FLUSH_CTRL is aimed to skip enabling
fWriteBoosterBufferFlushEn while WriteBooster is initializing.
Therefore it is better to apply the checking during WriteBooster
initialization only.
