Subject: [Qemu-devel] [PATCH 08/17] PPC: dbdma: Move defines into header file
Date: Mon, 1 Jul 2013 02:13:33 +0200 [thread overview]
Message-ID: <1372637622-50697-9-git-send-email-agraf@suse.de> (raw)
In-Reply-To: <1372637622-50697-1-git-send-email-agraf@suse.de>
We usually keep struct and constant definitions in header files. Move
them there to stay consistent and to make access to fields easier.
