These files were updated in this commit:
https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/commit/?id=2e92a49f90f73c8edc44b25c6e669d5e70893c90
"nvidia: update Tu10x and Tu11x signed firmware to support newer Turing HW20230404"

My hardware is Turing

it updates only sec2 files, but for more hardware than tu116/tu117

There is only one nvidia related commit between what's in our tree and
the one above:
https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/commit/nvidia?id=2c2be4215fe29870dcd9a059ff8778e73269ddc1
"nvidia: add GA102/GA103/GA104/GA106/GA107 signed firmware"
it only new files but doesn't change existing ones, so it should be harmless
to get this commit too, but our drm code won't make use of the new files.

So what should we do ?
- apply only 2e92a49f90f73c8edc44b25c6e669d5e70893c90 to our tree to get the
  updated sec2 files only
- or sync our tree with 2e92a49f90f73c8edc44b25c6e669d5e70893c90, getting
  the GA* firmware in the process that are useless for us ?

the extra files are 1MB

I did all this on a netbsd-10 kernel with modular-xorg, so I'd say yes :)
