Which is this WARN_ON in the driver:
/* expect using firmware supplicant for 1X */
ifp = netdev_priv(dev);
if (WARN_ON(ifp->vif->profile.use_fwsup != BRCMF_PROFILE_FWSUP_1X))
return -EINVAL;

That's not an oops and wpa_supplicant is not the "offending process", it
is just the user space process in which context the driver hits this
issue.

That should be reported to the maintainers of the kernel driver that has
this issue:
