Date: Tue, 11 Jan 2011 12:43:45 +0000 From: Jamie Iles <jamie@...ieiles.com> To: linux-kernel@...r.kernel.org Cc: Jamie Iles <jamie@...ieiles.com>, Kukjin Kim <kgene.kim@...sung.com>, linux-arm-kernel@...ts.infradead.org Subject: [PATCH 08/16] ARM: samsung: serial: 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.
