This whole patch is invalid, because of this part:

- info->fb_buffer = dma_alloc_coherent(NULL, fbinfo->fix.smem_len +
- ACTIVE_VIDEO_MEM_OFFSET,
- &info->dma_handle, GFP_KERNEL);
+ info->fb_buffer = dmam_alloc_coherent(&pdev->dev, NULL,
+ fbinfo->fix.smem_len +
+ ACTIVE_VIDEO_MEM_OFFSET,
+ &info->dma_handle, GFP_KERNEL);


dmam_alloc_coherent() is called with 5 arguments but only accepts 4.

Please ignore this whole patch altogether.

I am sorry about that.
