Correct, but we should bump the kernel headers, instead of just
modifying them manually. I've sent a small patch series that bumps them
to v6.7 already. I'm fine merging this with a commit message that
indicates it's a temporary local change until the corresponding code
gets merged in the kernel.

Let's also split this patch in two, with one patch for the kernel and
one for the rest. The second patch needs to update
src/ipa/rkisp1/algorithms/agc.cpp where we currently have a

	if (context.configuration.hw.revision < RKISP1_V12)

check that I believe isn't right anymore.
