  Hi,

This patchset introduces a new vb2_get_buffer accessor and then
uses it on all the drivers that are accessing videobuf2
private buffer array directly.

I'm skipping Intel IPU3 driver here, since the code goes beyond
just accessing the buffer. It also modifies the buffer queue
directly. I believe this driver would need some more cleanup
and love from its maintainers.

Note that OMAP2/OMAP3 display driver is videobuf1 and so not
affected by this change.

Lastly, note that I'm doing the minimum changes to drivers I can't test,
only using the new accessor and avoiding any further changes.

Changes from v1:

* Address feedback from Boris, and drop redundant check.

Thanks,
Ezequiel
