Subject: [PATCH v3 2/2] scsi: ufs: remove wrapper function ufshcd_setup_clocks()
Date:   Fri,  5 Jun 2020 22:05:20 +0200
Message-Id: <20200605200520.20831-3-huobean@gmail.com>
In-Reply-To: <20200605200520.20831-1-huobean@gmail.com>
References: <20200605200520.20831-1-huobean@gmail.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

From: Bean Huo <beanhuo@micron.com>

The static function ufshcd_setup_clocks() is just a wrapper around
__ufshcd_setup_clocks(), remove it. Rename original function wrapped
__ufshcd_setup_clocks() to new ufshcd_setup_clocks().
