I was going to apply this and patch 4 squashed, saying:


    cfg80211: regulatory: handle 6 GHz power spectral density (PSD)

    6 GHz regulatory domains introduce power spectral density (PSD).
    Allow wiphy-specific regulatory rules to specify these values.

This is obviously wrong?

Yes it should change like this:

	if ((rrule1->flags & NL80211_RRF_PSD) && (rrule1->flags & 
NL80211_RRF_PSD))
		chan->psd = min_t(s8, rrule1->psd, rrule1->psd);

One of those still should be rrule2 :)
