Yet another fix similar to 9134586715e3, 5f8d3ab136d0, which is needed to allow angler boot after 3edfb7bd76bd ("gpiolib: Show correct direction from the beginning"). Signed-off-by: Petr Vorel --- Changes v1->v2: * Remove <0 4> (not needed) * Remove from commit message: Fixes: 3edfb7bd76bd ("gpiolib: Show correct direction from the beginning") - although fix is needed after 3edfb7bd76bd, I'm not sure if this commit is to blame commits which added/modified DTS.
