Subject: [PATCH] pinctrl: bcm2835: Direct GPIO config changes to
generic pinctrl
commit b6e5531c0f80de2779c87d0235b4fde5310a83b5 upstream.
In order to support GPIO config changes direct these to the generic pinctrl.
This also requires an adjust of the return code for unsupported parameter
otherwise gpiod_configure_flags wont work as expected.
