From 1b5b20e51e290e58cc28a9a7cfb72178c0c10614 Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Fri, 13 Mar 2015 03:01:42 +0000 Subject: atheros: v3.18: rearrange code between patches Cleanup board patch by moving code to specific patches, and factor out leds to separate patch. No functional changes.
