4.0-stable review patch. If anyone has any objections, please let me know.
------------------
From: Wei Yongjun <yongjun_...@trendmicro.com.cn>
commit 932df43005389300a3336421e4aedb25390ae144 upstream.
In case of error, the function devm_ioremap() returns NULL
not ERR_PTR(). The IS_ERR() test in the return value check
should be replaced with NULL test.
Fixes: ecfe64d8c55f ("power: reset: Add AT91 reset driver")
