Subject[PATCH 1/2] pinctrl: Fix return value about devm_platform_ioremap_resource()
Date
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")
