From 0b2e9cb42cd0b5b0c95a776e30c9ecdff16587ea Mon Sep 17 00:00:00 2001 From: Jamie Iles <jamie@jamieiles.com> Date: Tue, 11 Jan 2011 12:43:42 +0000 Subject: [PATCH] s3c2410fb: don't treat NULL clk as an error clk_get() returns a struct clk cookie to the driver and some platforms may return NULL if they only support a single clock. clk_get() has only failed if it returns a ERR_PTR() encoded pointer.
