Subject: drm: Remove unneeded dma sync in ATI pcigart alloc
X-Git-Tag: v2.6.26-rc1~1048^2~5
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=f1c3e67eb73a4a1db31e235883156ac098e29ff6;p=linux-2.6

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.
