Unfortunately this series no longer applies. Support for the G2/HEVC decoder
was merged, and that conflicts with this series.

It is best to rebase you series to the master branch of the media_stage
tree (https://git.linuxtv.org/media_stage.git/log/), which contains that
series. I expect/hope that this will be merged later this week to the
regular media_tree master branch, so you can wait for that as well.

Regards,

	Hans
