Hi Mike,
Do you have any comments about this patch?
The patch is needed to provide a clean fix for recently
broken support for HDMI on Exynos4210 SoC in mainline.

Tomasz Stanislawski

Most operations on DMA and DMABUF framework need page
aligned buffers. This fix guarantees this requirement
for vb2-dma-contig buffers.

The DMA transfer must be aligned to a specific value. If userptr is not aligned
to DMA requirements then unexpected corruptions of the memory may occur before
or after a buffer. To prevent such situations, all unligned userptr buffers
are rejected at VIDIOC_QBUF.

whole buffer's lifetime. Therefore MMAP buffers should take a reference to the
device to avoid risk of dangling pointers.
