   4 Subject: [PATCH] pinctrl: bcm2835: Direct GPIO config changes to
   5  generic pinctrl
   6
   7 commit b6e5531c0f80de2779c87d0235b4fde5310a83b5 upstream.
   8
   9 In order to support GPIO config changes direct these to the generic pinctrl.
  10 This also requires an adjust of the return code for unsupported parameter
  11 otherwise gpiod_configure_flags wont work as expected.
