Subject: [PATCH v4 3/8] scsi: ufs: Remove the check before call setup clock notify vops
Date: Wed, 22 Jan 2020 23:25:44 -0800	[thread overview]
Message-ID: <1579764349-15578-4-git-send-email-cang@codeaurora.org> (raw)
In-Reply-To: <1579764349-15578-1-git-send-email-cang@codeaurora.org>

The functionality of vendor specific ops should be handled properly in
platform specific driver, but should not count on the UFS driver.
