From: Hans Verkuil Date: Mon, 21 Mar 2016 11:07:44 +0000 (-0300) Subject: [media] tw686x-kh: specify that the DMA is 32 bits X-Git-Tag: v4.7-rc1~130^2~81 X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=304d2a7fc8acc1bb337596e0fc301092ea079b4d;p=karo-tx-linux.git [media] tw686x-kh: specify that the DMA is 32 bits Set vb2_queue.gfp_flags to GFP_DMA32. Otherwise it will start to create bounce buffers which is something you want to avoid since those are in limited supply.
