Title:
Broadcom BCM4356 wifi chipset firmware is not working
Status in linux-firmware package in Ubuntu:
Incomplete
Bug description:
Hello,
After upgrading to Ubuntu 18.04 I got an issue with the wifi chipset
(Broadcom BCM4356) not initializing properly.
Here is the error I got when loading the driver brcmfmac:
```
[ 8189.092819] brcmfmac: brcmf_fw_map_chip_to_name: using
brcm/brcmfmac4356-pcie.bin for chip 0x004356(17238) rev 0x000002

```
As seen here https://answers.launchpad.net/ubuntu/+question/668329, I
reverted to the previous linux-firmware version and then the wifi
chipset is working:

The problem seems to have been reported to the linux-wireless mailing
list but no fix has been committed apparently :
