Subject: [PATCH v5 12/13] scsi: ufs: need to check whether sshdr is valid in ufshcd_set_dev_pwr_mode
Date: Fri, 18 Oct 2019 16:24:30 +0800 [thread overview]
Message-ID: <1571387071-28853-13-git-send-email-zhengbin13@huawei.com> (raw)
In-Reply-To: <1571387071-28853-1-git-send-email-zhengbin13@huawei.com>
Like sd_pr_command, before use sshdr, we need to check whether
sshdr is valid.
