From: Tiezhu Yang <yangtiezhu@loongson.cn>
[ Upstream commit b5d9ff10dca49f4d4b7846c3751c6bec50d07375 ]
When call function devm_platform_ioremap_resource(), we should use IS_ERR()
to check the return value and return PTR_ERR() if failed.
Fixes: 4b024225c4a8 ("pinctrl: use devm_platform_ioremap_resource() to simplify code")
