Subject: [Intel-gfx] [PATCH 1/4] drm/i915: Fix the sgt.pfn sanity check
Date: Tue, 19 Jan 2021 13:31:03 +0000	[thread overview]
Message-ID: <20210119133106.66294-1-matthew.auld@intel.com> (raw)

From: Kui Wen <kui.wen@intel.com>

For the device local-memory case, sgt.pfn will always be equal to zero,
since we instead use sgt.dma. Also, for device local-memory it is
perfectly valid for it to start from zero anyway, so no need to add a
new check for that either.
