Subject: [PATCH net-next 3/4] can: can-dev: remove obsolete CAN LED support
From: Oliver Hartkopp <socketcan@...tkopp.net>
Since commit 30f3b42147ba6f ("can: mark led trigger as broken") the
CAN specific LED support was disabled and marked as BROKEN. As the
common LED support with CONFIG_LEDS_TRIGGER_NETDEV should do this work
now the code can be removed as preparation for a CAN netdevice Kconfig
rework.
