[ 05/73] pwm: spear: Fix checking return value of clk_enable() and clk_prepare()

[Greg Kroah-Hartman]

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

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

From: Axel Lin <axel.lin@xxxxxxxxxx>

commit 563861cd633ae52932843477bb6ca3f1c9e2f78b upstream.

The logic to check return value of clk_enable() and clk_prepare() is reversed,
fix it.
