Subject: [PATCH 3/5] leds: trigger: netdev: Rename add namespace to netdev
|
|
trigger enum modes
|
|
|
|
Rename NETDEV trigger enum modes to a more symbolic name and add a
|
|
namespace to them.
|
|
|
|
Also add __TRIGGER_NETDEV_MAX to identify the max modes of the netdev
|
|
trigger.
|
|
|
|
This is a cleanup to drop the define and no behaviour change are
|
|
intended.
