Arend,

Commit 9390ace "brcmfmac: free net device when registration fails"
causes a regression.

I had the BCM4330 firmware present in my root fs, whereas my HW is a
BCM4329. With this patch applied, I get a kernel panic on boot. With it
reverted, I see that no issues of that nature. This is true in
next-20130531 (and also 5/30 and 6/1 but not earlier). A bisect of
Linus's tree followed by a merge of John's wireless pull request from
today pointed at this same commit.

Thanks, Stephen

I will look into this.

Hi Stephen,

Can you try the attached patch? If it does not solve the issue, could
you provide a log.

Yes, that works great, thanks.

Did this patch get applied anywhere? I was hoping it'd go into 3.10-rc*
given it's a user-triggerable backtrace introduced in 3.10-rc*.

Hi Stephen,

The patch went into the wireless-next tree. Given recent events with our patch series I am a bit more carsful to tag patches for 3.10. Your issue is user-triggerable but the scenario to get there can be avoided. But you are right it was introduced in the 3.10-rc cycle. I leave it to John to decide.

Regards,
Arend
