From bec69de89bab29c739ab84ceb04ae63d6811babf Mon Sep 17 00:00:00 2001 From: Heiner Kallweit Date: Wed, 14 Sep 2016 20:55:18 +0200 Subject: leds: gpio: fix and simplify reading property "label" Checking for the presence of the property first isn't strictly needed as we can react on the return code of fwnode_property_read_string. Also, even if the presence of a property "label" was checked, reading a string value for it theoretically still can fail and this case isn't handled.
