Subject: [PATCH v2 2/2] scsi: ufs: Uninline ufshcd_vops_device_reset function
Date: Tue, 8 Dec 2020 21:56:35 +0800	[thread overview]
Message-ID: <20201208135635.15326-3-stanley.chu@mediatek.com> (raw)
In-Reply-To: <20201208135635.15326-1-stanley.chu@mediatek.com>

Since more and more statements showing up in ufshcd_vops_device_reset(),
uninline it to allow compiler making possibly better optimization.
