Thanks for testing!

I just sent a 26 patch series to address this issue. There are 4 patches
on it that affects cinergyT2 (one is this patch, but the other ones
should be addressing other problems there).

Could you please test them, and if they're ok, reply to me with a
Tested-by: tag?

PS.: I'm also putting those patches on my development tree, at:
	git://git.linuxtv.org/mchehab/experimental.git media_dmastack_fixes

(please notice that my tree is based on Kernel 4.8 - so, to test with
VMAP_STACK, you'll likely need to pull also from Linus tree)

Thanks,
Mauro
