Subject: [RFC PATCH v3 4/8] leds: trigger: netdev: rename and expose NETDEV trigger enum modes
Date:   Tue,  9 Nov 2021 03:26:04 +0100
Message-Id: <20211109022608.11109-5-ansuelsmth@gmail.com>

Rename NETDEV trigger enum modes to a more simbolic name and move them
in leds.h to make them accessible by any user.
