  Hello,

While working on adding the V4L2-PIX-FMT-Y12P and V4L2-PIX-FMT-Y14P
formats, I noticed an issue in the way V4L2-PIX-FMT-Y10P is described.
This series aims to solve it before adding Y12P and Y14P.

Those two formats are needed for the next-to-come bcm2835 unicam driver.

I'll take the first patch, but it is better to add patches 2 and 3 to the unicam RFC
series. Adding pixelformats that are not used by any existing driver isn't a good idea
and I'd like to avoid that.

Regards,

Thanks, I will take those two patches back in the unicam RFC v2 series then.
