Various bug/regression fixes for 3.17

Hi Mauro,

This collects my set of 3.17 patches, including the vb2 poll regression fix.

I have also included the poll documentation fixes here, but if you prefer to add those to 3.18 instead, then that's fine by me.

Besides this pull request for 3.17 I have two other pull requests for 3.17 as well that have not yet been merged:

https://patchwork.linuxtv.org/patch/25162/
https://patchwork.linuxtv.org/patch/25824/

And this cx18 fix for 3.17 is currently in your fixes branch, but not yet
upstream: https://patchwork.linuxtv.org/patch/25572/

Regards,

Hans
