From 77dce3a22e8941552a15046d4113df9ce132fb3d Mon Sep 17 00:00:00 2001 From: Pavel Machek Date: Mon, 3 Aug 2020 14:00:06 +0200 Subject: leds: disallow /sys/class/leds/*:multi:* for now All the LEDs in the queue are RGB, so they should not use multi for their color. Make sure we don't add such LED by mistake (and make it part of ABI).
