The various devm_ functions allocate memory that is released when a driver
detaches.  This patch uses these functions for data that is allocated in
the probe function of a platform device and is only freed in the remove
function.

Acked-by: Mike Frysinger <redacted>

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.
