Subject: [RFC PATCH v6 04/11] leds: trigger: netdev: rename and expose NETDEV trigger enum modes
Date: Tue,  3 May 2022 17:16:26 +0200	[thread overview]
Message-ID: <20220503151633.18760-5-ansuelsmth@gmail.com> (raw)
In-Reply-To: <20220503151633.18760-1-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.
