Subject: [RESENT PATCH v5 1/5] scsi: ufs: remove max_t in ufs_get_device_desc
Date: Wed, 3 Jun 2020 11:19:55 +0200 [thread overview]
Message-ID: <20200603091959.27618-2-huobean@gmail.com> (raw)
In-Reply-To: <20200603091959.27618-1-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.
