Subject: [Qemu-devel] [RFC 12/14] vga: Rename vga_template.h to vga-helpers.h
Date: Tue, 24 Jun 2014 09:11:06 +1000 [thread overview]
Message-ID: <1403565068-15229-13-git-send-email-benh@kernel.crashing.org> (raw)
In-Reply-To: <1403565068-15229-1-git-send-email-benh@kernel.crashing.org>
It's no longer a template, we only instanciate the file once.
Keep it a #included file so the functions remain static.
