3.2-stable review patch. If anyone has any objections, please let me know.
------------------ From: Wei Yongjun <yongjun_...@trendmicro.com.cn> commit f61bd0585dfc7d99db4936d7467de4ca8e2f7ea0 upstream. In case of error, the function clk_get() returns ERR_PTR() and never returns NULL pointer. The NULL test in the error handling should be replaced with IS_ERR(). dpatch engine is used to auto generated this patch.
