Subject: [Nouveau] [PATCH 2/7] vgaarb: remove vga_conflicts
Date: Fri, 16 Jul 2021 08:16:29 +0200	[thread overview]
Message-ID: <20210716061634.2446357-3-hch@lst.de> (raw)
In-Reply-To: <20210716061634.2446357-1-hch@lst.de>

vga_conflicts only has a single caller and none of the arch overrides
mentioned in the comment.  Just remove it and the thus dead check in the
caller.
