Subject: [regression] Bug 216894 - brcmfmac stopped working due to missing firmware; brcmf_pcie_init_ringbuffers: invalid max_flowrings(264)

Hi, this is your Linux kernel regression tracker.

I noticed a regression report in bugzilla.kernel.org. As many (most?)
kernel developer don't keep an eye on it, I decided to forward it by
mail. Quoting from https://bugzilla.kernel.org/show_bug.cgi?id=216894 :

See the ticket for more details.

BTW, let me use this mail to also add the report to the list of tracked
regressions to ensure it's doesn't fall through the cracks:

#regzbot introduced: 2aca4f3734bd717e04943
https://bugzilla.kernel.org/show_bug.cgi?id=216894
#regzbot title: net: wifi: brcmfmac stopped working as firmware is not
loaded anymore
#regzbot ignore-activity

Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat)
