Subject: [Nouveau] [PATCH 4/7] vgaarb: cleanup vgaarb.h
Date: Fri, 16 Jul 2021 08:16:31 +0200	[thread overview]
Message-ID: <20210716061634.2446357-5-hch@lst.de> (raw)
In-Reply-To: <20210716061634.2446357-1-hch@lst.de>

Merge the different CONFIG_VGA_ARB ifdef blocks, remove superflous
externs, and regularize the stubs for !CONFIG_VGA_ARB.
