Subject: base-files: configure LED when added
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=511e8f84d093b6fbb93b044c2ab150e613b88171;p=openwrt%2Fstaging%2Fansuel.git

base-files: configure LED when added

Currently LED configuration is only carried out once during boot.
Apply LED configuration also with a hotplug call when a new LED gets
added later.
