From 1fb6dd9da6ed4f2953b62162f3c498a1f6d7bfca Mon Sep 17 00:00:00 2001 From: Leo Yan Date: Mon, 3 Aug 2015 09:13:34 +0800 Subject: [PATCH] clk: hisi: refine parameter checking for init *of_iomap()* will check the device node pointer, and if the pointer is NULL it will return error code. So refine clock's init flow by checking the device node with this simple way; and polish a little for the print out message.
