I apologise if my report is lacking in detail; it is my first attempt at bug/issue reporting in the kernel.
Please follow up if something is missing, or more detail/testing is required.
It is certainly possible for me to provide more oops reports if required, as they generally surface at least once a day.
Thank you.

Oops - Null pointer dereference in brcm80211/brcmfmac [BCM4350]
[2.]
Seemingly randomly, when connected to a wireless network, my laptop will begin failing to tx/rx data, and begin repeatedly reporting the following messages in the kernel ring buffer:
```
[18990.872335] brcmfmac: brcmf_cfg80211_get_station: GET STA INFO failed, -12
[18990.872433] brcmfmac: brcmf_msgbuf_tx_ioctl: Failed to reserve space in commonring
[18990.872439] brcmfmac: brcmf_cfg80211_get_tx_power: error (-12)
```
Upon trying to rmmod && modload brcmfmac, I receive the oops dump included below, and am unable to continue using the wireless NIC until I reboot.
This does not appear to have a pattern, except that it usually happens at least once throughout a day of work.
It has been happening at least since 4.20.4, but potentially earlier (this machine wasn't in heavy use before then).

No apologies needed. I am generally happy with kernel log and short
context description.

The "reserve space" issue has been reported before although I have not
looking into it yet.

I will look into the NULL pointer access.

No worries, the only reason I included it is that it seems to appear as soon as traffic starts to fail, which then prompts me to `rmmod brcmfmac`, which triggers the oops.

Great news. Please let me know if you require me to gather any more information.
Thank you.

FullMAC firmware (the one running on card's ARM CPU) has crashed.

Interestingly I've experienced the same problem (for the first time)
last week. I started working on it but didn't achieve anything yet.
