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	[thread overview]
Message-ID: <20201222072905.32221-3-stanley.chu@mediatek.com> (raw)
In-Reply-To: <20201222072905.32221-1-stanley.chu@mediatek.com>

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.
