Subject: [PATCH v3 1/5] scsi: ufs: Remove unnecessary memset for dev_info
Date: Sun, 17 May 2020 01:46:11 +0800 [thread overview]
Message-ID: <20200516174615.15445-2-stanley.chu@mediatek.com> (raw)
In-Reply-To: <20200516174615.15445-1-stanley.chu@mediatek.com>
The whole UFS host instance has been zero-initialized by
scsi_host_alloc(), thus UFS driver does not need to clear
"dev_info" member specifically in ufshcd_device_params_init().
Simply remove the unnecessary code.
