Yeah, something like that would be really nice. It would also make it
easier for me to update linux-firmware.git.

What about if we had a script which installs the latest ath10k firmware
files from ath10k-firmware.git? Something along lines of:

$ cd ~/git/ath10k-firmware
$ git pull
$ sudo ath10k-fw-install /lib/firmware/ath10k

I could also add a simple menu to select older firmware versions. But
this is just a wild idea.
