[PATCH -next] clocksource: keystone: Fix return value check in keystone_timer_init()

From: Wei Yongjun
Date: Thu Jan 16 2014 - 03:29:07 EST

From: Wei Yongjun <yongjun_wei@xxxxxxxxxxxxxxxxx>

In case of error, function of_clk_get() returns ERR_PTR()
and never returns NULL. The NULL test in the return value
check should be replaced with IS_ERR().
