From 8431712fa81721de1e675d98f19d2de9ddc96195 Mon Sep 17 00:00:00 2001 From: Thierry Reding Date: Fri, 30 Aug 2013 12:32:18 +0200 Subject: pwm-backlight: Use new enable_gpio field Make use of the new enable_gpio field and allow it to be set from DT as well. Now that all legacy users of platform data have been converted to initialize this field to an invalid value, it is safe to use the field from the driver.
