Subject: gpio: propagate of_parse_phandle_with_args errors
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=41920d16360ebc8c482911078a17d9994fb77612;p=openwrt%2Fstaging%2Fblogic.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.
