    Subject[PATCH 5.10 041/199] scsi: ufs: Relax the condition of UFSHCI_QUIRK_SKIP_MANUAL_WB_FLUSH_CTRL
    Date
    From: Stanley Chu <stanley.chu@mediatek.com>

    [ Upstream commit 21acf4601cc63cf564c6fc1a74d81b191313c929 ]

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