Fix
Comment 3 Stanislaw Gruszka 2014-03-05 13:44:24 UTC 
Josh, please apply above patch as fix for this bug, it is just WARN_ONCE remove.
Comment 4 Josh Boyer 2014-03-06 14:24:25 UTC 
I had to change it to apply to bt-coex.c instead of coex.c.  I'm assuming there was a file rename in net-next or something.

Thanks Emmanuel and Stanislaw.
Comment 5 Emmanuel Grumbach 2014-03-06 14:27:59 UTC 
yeah... patch isn't in -next yet even...
in any case, the patch is already in wireless.git (on the right file)
