Subject: [PATCH 6/7] drm/tilcdc: clean up ifdef hacks around iowrite64
Date: Thu, 22 Jun 2017 10:48:16 -0600	[thread overview]
Message-ID: <20170622164817.25515-7-logang@deltatee.com> (raw)
In-Reply-To: <20170622164817.25515-1-logang@deltatee.com>

Now that we can expect iowrite64 to always exist the hack is no longer
necessary so we just call iowrite64 directly.
