Subject: Re: [PATCH v5 00/49] DaVinci: vpif: upgrade with v4l helpers and
 v4l compliance fixes

Hi Prabhakar,

Thanks for this patch series, it looks good to me and I'll make a pull
request for this.

I did find a few issues, but they are all pre-existing problems, so they
can be fixed in follow-up patches.

I'll comment on those in the relevant patches. Since display and capture are
so similar I will only comment on the display patches, but it's valid for
both.

Regards,

	Hans
