[PATCH v3] wifi: cfg80211: call reg_notifier for self managed wiphy from driver hint

[Johannes Berg]

Hi Wen,

Yeah. Actually, I saw v3 only after I merged v2, but then I saw what the
change was and figured that was unnecessary anyway.

Indeed. The point of the comment saying "use" was to actually, well,
_use_ the hole next time. I haven't really enforced that since I keep
forgetting (and we're nowhere near running out of bits), but yes, the
point is that you could even have used bit 11 or 12.

I guess it could use another bit number (such as 11) in a backport, but
I don't see that this really _needs_ to be backported? And if you're
using backports to backport the whole wifi stack then this isn't even a
question since it all comes in backports.
