Title:
  No wlan interfaces found on CM4 after firmware update

Status in linux-firmware-raspi2 package in Ubuntu:
  New

Bug description:
  During testing of image http://cdimage.ubuntu.com/ubuntu-server/focal
  /daily-preinstalled/pending/focal-preinstalled-server-
  arm64+raspi.img.xz it was noted that the WLAN interface was missing.

  It appears that the introduction of package version 3-0ubuntu1~20.04.1
  results in breakage of WLAN on CM4 devices.

  No interface is listed on completion of boot.
