From 50c01fc355c6a97c511d58411f9bc0e4b8fc4659 Mon Sep 17 00:00:00 2001 From: Jamie Iles Date: Tue, 11 Jan 2011 12:43:52 +0000 Subject: spi/dw_spi: 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.
