TL;DR we don't need a Fixes: for your v2.

Pardon me, not a Fixes: the sizeof(sensor) that can be supported is SoC 
specific - camera IP specific really - so 8192 is a blunt descriptor, 
raising to 16384 makes some kind of sense.

A long term fix for this would be for each camss descriptor to declare 
the maximum sizeof(sensor) it supports. For sm8250, sc8280xp that's 64 
megapixels - for older SoCs its going to be smaller.
