Subject: [PATCH 1/3] gpio: bcm-kona: Fix return value of bcm_kona_gpio_probe()
Date: Fri, 22 May 2020 12:12:18 +0800 [thread overview]
Message-ID: <1590120740-22912-1-git-send-email-yangtiezhu@loongson.cn> (raw)
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()")
