[PATCH AUTOSEL 5.6 315/606] gpio: pxa: Fix return value of pxa_gpio_probe()

[Sasha Levin]

From: Tiezhu Yang <yangtiezhu@xxxxxxxxxxx>

[ Upstream commit 558ab2e8155e5f42ca0a6407957cd4173dc166cc ]

When call function devm_platform_ioremap_resource(), we should use IS_ERR()
to check the return value and return PTR_ERR() if failed.

Fixes: 542c25b7a209 ("drivers: gpio: pxa: use devm_platform_ioremap_resource()")
