Every time the package linux-firmware-raspi2 is updated, the file brcmfmac43455-sdio.bin is rewritten and this error occurs:

Jul 04 14:34:42 ubuntu kernel: brcmfmac: brcmf_sdio_hostmail: mailbox indicates firmware halted
Jul 04 14:34:45 ubuntu kernel: brcmfmac: brcmf_sdio_bus_rxctl: resumed on timeout
Jul 04 14:34:48 ubuntu kernel: brcmfmac: brcmf_sdio_bus_rxctl: resumed on timeout

Jul 04 14:34:55 ubuntu kernel: brcmfmac: brcmf_cfg80211_scan: scan error (-110)

I must copy by hand the file brcmfmac43455-sdio.bin to solve this problem, from:

https://github.com/RPi-Distro/firmware-nonfree/raw/master/brcm/brcmfmac43455-sdio.bin

Please, I ask you to update the file brcmfmac43455-sdio.bin in the package linux-firmware-raspi2 (1.20180919-0ubuntu0.18.04.2).

Note: the package linux-firmware (1.173.8) also has this file brcmfmac43455-sdio.bin
