Subject: [PATCH v7 2/7] scsi: ufs: use an enum for host capabilities
Date: Wed, 18 Mar 2020 18:40:11 +0800 [thread overview]
Message-ID: <20200318104016.28049-3-stanley.chu@mediatek.com> (raw)
In-Reply-To: <20200318104016.28049-1-stanley.chu@mediatek.com>
Use an enum to specify the host capabilities instead of #defines inside the
structure definition.
