From 4d3ae5a9a7b3685c6d260a82f4098145862b2cd3 Mon Sep 17 00:00:00 2001 From: Benoit Cousson Date: Thu, 20 May 2010 12:31:09 -0600 Subject: OMAP: hwmod: Remove IS_ERR check with omap_clk_get_by_name return value The previous clock API was returning a standard linux error code in case of failure. This is not the case anymore with the new omap_clk_get_by_name API. A NULL value means that the clock node does not exist. Replace all the IS_ERR check by a !clk check.
