From b2987d7438e0ca949d81774ca8b43d370a1f9947 Mon Sep 17 00:00:00 2001 From: Alexander Stein Date: Thu, 12 Jan 2017 17:39:24 +0100 Subject: gpio: Pass GPIO label down to gpiod_request Currently all users of fwnode_get_named_gpiod() have no way to specify a label for the GPIO. So GPIOs listed in debugfs are shown with label "?". With this change a proper label is used. Also adjust all users so they can pass a label, properly retrieved from device tree properties.
