Public bug reported:
A recent update of linux-firmware 'fixed' dangling symlinks and now the
raspi kernel tries to load brcm/brcmfmac43430-sdio.clm_blob from the
linux-firmware package but uses the FW blob brcm/brcmfmac43430-sdio.bin
from the linux-firmware-raspi2 package. The two don't play well
together:
$ sudo dmesg | grep brcm

[ 18.059280] brcmfmac: brcmf_sdio_firmware_callback: brcmf_attach failed
The FW blob from linux-firmware-raspi already contains CLM data and
doesn't need to load a dedicated blob. In fact it must not, so linux-
firmware-raspi2 needs to divert brcm/brcmfmac43430-sdio.clm_blob from
the linux-firmware package.
