Subject: [PATCH] leds: Standardise LED naming scheme
As discussed on LKML some notion of 'function' is needed in
LED naming. This patch adds this to the documentation and
standardises existing LED drivers.

Is currently of the form:
-"devicename:colour"
+"devicename:colour:function"
There have been calls for LED properties such as colour to be exported as
individual led class attributes. As a solution which doesn't incur as much
overhead, I suggest these become part of the device name. The naming scheme
-above leaves scope for further attributes should they be needed.
+above leaves scope for further attributes should they be needed. If sections
+of the name don't apply, just leave that section blank.
