Re: [PATCH 2/6] [media] Documentation: Add HSV format
From: Mauro Carvalho Chehab
Date: Fri Jul 15 2016 - 11:28:57 EST
Hi Ricardo,
I'm not seeing patch 1.
Anyway, please send documentation patches against the rst files. They're
at the "docs-next" branch and will be merged upstream on this merge window.
After its merge, we'll drop the DocBook.
Thanks,
Mauro
