Subject: gpio: propagate of_parse_phandle_with_args errors
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=41920d16360ebc8c482911078a17d9994fb77612;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

gpio: propagate of_parse_phandle_with_args errors

Make of_get_named_gpio_flags propagate any error it receives from
of_parse_phandle_with_args instead of inconditionally returning -EINVAL.
