Subject: [PATCH leds 4/8] leds: turris-omnia: Use global header for MCU command definitions
Date: Mon,  2 Sep 2024 14:41:00 +0200	[thread overview]
Message-ID: <20240902124104.14297-5-kabel@kernel.org> (raw)
In-Reply-To: <20240902124104.14297-1-kabel@kernel.org>

The global turris-omnia-mcu-interface.h header file contains the
definitions for MCU commands. Drop the driver-internal definitions and
use the global ones.
