(I probably should have waited before writing a patch doing exactly
that, hopefully i didn't tested it

I will just mention that "all the mediatek firmwares" also include more
files in linux-firmware's mediatek/ directory. But the situation there
is more complicated. the mt76/btmtk drivers are still under active
development, and they will stop using some firmware files.)

Well, currently the menuconfig for bluetooth and wifi are splitted.

And in this case, there is no firmware that is specific to a WiFi/BT
combo chip. The mt7662.bin file is used by both wifi and wifi/bt combos
and so is mt7650.bin for bt and wifi/bt.
