Subject: [PULL 13/20] nubus-bridge: introduce separate NubusBridge structure
Date: Wed, 29 Sep 2021 11:28:36 +0200	[thread overview]
Message-ID: <20210929092843.2686234-14-laurent@vivier.eu> (raw)
In-Reply-To: <20210929092843.2686234-1-laurent@vivier.eu>

From: Mark Cave-Ayland <mark.cave-ayland@ilande.co.uk>

This is to allow the Nubus bridge to store its own additional state. Also update
the comment in the file header to reflect that nubus-bridge is not specific to
the Macintosh.
