Subject: [PATCH v4 01/10] scsi: ufs: Export ufshcd_uic_change_pwr_mode()
Date: Wed, 15 Jun 2022 11:51:37 +0800	[thread overview]
Message-ID: <20220615035146.20964-2-stanley.chu@mediatek.com> (raw)
In-Reply-To: <20220615035146.20964-1-stanley.chu@mediatek.com>

Export ufshcd_uic_change_pwr_mode() to allow vendors to
use it for SoC-specific power mode change design limitation.
