5.12.0 amber is not the same as git

And also not the same as the version tagged pureos/5.12.0pureos1_amber1 (51b1d9a3).

I confirmed this by compiling that version myself. Logs captured using:

purism@pureos:~$ sudo modprobe s5k3l6xx debug=5
purism@pureos:~$ echo 'file drivers/media/platform/* +p' | sudo tee /sys/kernel/debug/dynamic_debug/control
file drivers/media/platform/* +p
purism@pureos:~$ v4l2-ctl -d 1 --set-fmt-video=width=2000,height=2000,pixelformat=GRBG

Correct output is nothing, but Amber .deb version here gives:

VIDIOC_S_FMT: failed: Invalid argument

logs:
