From fca23e47dfdbcdacaae523f8b87d2240ce056ac1 Mon Sep 17 00:00:00 2001 From: "Andrew F. Davis" Date: Tue, 21 Jun 2016 14:40:11 +0200 Subject: [PATCH] leds: Add no-op gpio_led_register_device when LED subsystem is disabled Some systems use 'gpio_led_register_device' to make an in-memory copy of their LED device table so the original can be removed as .init.rodata. When the LED subsystem is not enabled source in the led directory is not built and so this function may be undefined. Fix this here. Signed-off-by: Andrew F.
