Subject: [PATCH 1/7] drm: helper macros to print composite types
Date: Sat,  5 Nov 2016 11:08:06 -0400	[thread overview]
Message-ID: <1478358492-30738-2-git-send-email-robdclark@gmail.com> (raw)
In-Reply-To: <1478358492-30738-1-git-send-email-robdclark@gmail.com>

I'll want to print things in a similar way in a later patch.  This will
make it easier.
