Can someone please > help me on this? I have the hardware, but this driver is not testable right now as it is in the mainline since the board code for the camera is missing from N8[01]0 (besides cbus driver AFAIR). However the change seems practically mandatory to me --- I can ack it if you send a patch against omap24xxcam.c, as your new patch no longer contains the change for omap24xxcam.c. Thanks.
As per Vaibhav's review comments, I have split the patch into 2 different (independent) patches: - one for omap_vout - and another for omap24xxcam.c (name changed to [PATCH] OMAP2: V4L2: Remove GFP_DMA allocation as ZONE_DMA is not configured on OMAP ) If you have difficulty in finding it I can send it again. Thanks, Amber

Remove GFP_DMA from the __get_free_pages() call as ZONE_DMA is not configured on OMAP. Earlier the page allocator used to return a page from ZONE_NORMAL even when GFP_DMA is passed and CONFIG_ZONE_DMA is disabled. As a result of commit a197b59ae6e8bee56fcef37ea2482dc08414e2ac, page allocator returns null in such a scenario with a warning emitted to kernel log.
