Subject: [ 142/167] [PATCH] i2c: pnx: Disable clk in suspend

3.2-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Roland Stigge <stigge@...com.de>

commit 6c557cfee08751d22aed34840f389b846f0f4508 upstream.

In the driver's suspend function, clk_enable() was used instead of
clk_disable(). This is corrected with this patch.
