Subject: [PATCH v2 2/6] drm/v3d: Drop unused v3d_flush_caches().
Date: Mon,  3 Dec 2018 14:24:34 -0800	[thread overview]
Message-ID: <20181203222438.25417-2-eric@anholt.net> (raw)
In-Reply-To: <20181203222438.25417-1-eric@anholt.net>

Now that I've specified how the end-of-pipeline flushing should work,
we're never going to use this function.
