Subject[PATCH 1/3] gpio: bcm-kona: Fix return value of bcm_kona_gpio_probe()
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: 72d8cb715477 ("drivers: gpio: bcm-kona: use devm_platform_ioremap_resource()")
