Hi Johannes,

I tested the patch on x86 platform and was successful executing a 
p2p_find, p2p_connect, and able to ping my peer. But....

When I tried this a second time I got a lockdep warning about annotation 
as brcmfmac tried to take a mutex during scan (p2p_find). Two minutes 
later I got warning about rcu stalls. Not sure where to look.

Gr. AvS
