# The above pattern works because the files we want to hit
# have names of the form:
# * /lib/firmware/brcm/brcmfmac43430-sdio.AP6212.txt
# * /lib/firmware/brcm/brcmfmac43430-sdio.Hampoo-D2D3_Vi8A1.txt

# * /lib/firmware/brcm/brcmfmac43455-sdio.raspberrypi,4-model-b.txt
# While the files installed by raspberrypi-wifi-ucode have names
# of the form:
# * /lib/firmware/brcm/brcmfmac43430-sdio.txt

# So no overlap is assured.
