Subject: drm: Remove unneeded dma sync in ATI pcigart alloc
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=f1c3e67eb73a4a1db31e235883156ac098e29ff6;p=deliverable%2Flinux.git

drm: Remove unneeded dma sync in ATI pcigart alloc

Now that the ATI pcigart code uses dma_alloc_coherent, we don't need
the dma_sync_single_for_device() that we used to have here.
