PKGBUILDs/alarm/uboot-boundary/0006-common-board_f-cosmetic-use-__weak-for-leds.patch

From 137c23ed9e6ad2cba575842065bffa6e59170e17 Mon Sep 17 00:00:00 2001
From: Jeroen Hofstee <jeroen@myspectrum.nl>

Subject: [PATCH 6/6] common: board_f: cosmetic use __weak for leds

First of all this looks a lot better, but it also
prevents a gcc warning (W=1), that the weak function
has no previous prototype.
