Subject: [PATCH v2 1/3] scsi: ufs: remove max_t in ufs_get_device_desc
Date: Thu, 28 May 2020 13:56:14 +0200 [thread overview]
Message-ID: <20200528115616.9949-2-huobean@gmail.com> (raw)
In-Reply-To: <20200528115616.9949-1-huobean@gmail.com>
From: Bean Huo <beanhuo@micron.com>
For the UFS device, the maximum descriptor size is 255, max_t called in
ufs_get_device_desc() is useless.
