Why would you need all the other fields besides req_sizes[]?
Which drivers actually need those other fields? Drivers like
exynos4-is/fimc-lite.c
don't actually use anything but req_sizes if you read the code carefully.
I suspect any driver that uses more than req_sizes is actually buggy or
written carelessly.
I wish you'd checked with me before making this struct...
Be aware that I'm abroad (vacation/conferences) from tomorrow until October 10,
so I won't be able to do in-depth reviews during that time (well, I'm able,
but I don't want to!)
Regards,
Hans
