Subject: pinctrl: Fix return value check in amd_gpio_probe()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=424a6c607c169ca0ac8431424f28fc839b45b14c;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

pinctrl: Fix return value check in amd_gpio_probe()

In case of error, the function devm_ioremap_nocache() returns NULL
pointer not ERR_PTR(). The IS_ERR() test in the return value check
should be replaced with NULL test.
