Sure, I have combined the two patches in one patch now:

So now you should probably resend it properly, with a new subject that
explains it better? Just "modify" doesn't really seem all that
appropriate - what's the modification?

Patchwork also lost half the patch for some reason, probably you
copy/pasted it and lost some whitespace at an empty line.

We have posted a new patch-set with better commit title and message.

Call the regulatory notifier for self managed hints only if
initiator is NL80211_REGDOM_SET_BY_USER and hint type is
NL80211_USER_REG_HINT_CELL_BASE. Also call regulatory
notifier when wiphy is registered under similar conditions.

I guess this should say why.

  	list_for_each_entry(rdev, &cfg80211_rdev_list, list) {
  		wiphy = &rdev->wiphy;
-		if (wiphy->regulatory_flags & REGULATORY_WIPHY_SELF_MANAGED)
+		if (wiphy->regulatory_flags & REGULATORY_WIPHY_SELF_MANAGED) {
  			self_managed_found = true;
-		else
-			return false;
+			if (request->initiator == NL80211_REGDOM_SET_BY_USER &&
+			    request->user_reg_hint_type ==
+			    NL80211_USER_REG_HINT_CELL_BASE)
+				reg_call_notifier(wiphy, request);
+		} else {
+			self_managed_found = false;
+		}
  	}

This is awkward now - how about

self_managed_found = regulatory_flags & SELF_MANAGED;
if (self_managed_found &&
    request->initiator == ... &&
    ...)
        reg_call_notifier(...)

This has been addressed in the new patch with a separate notify function.

no need to change the indentation here

has been addressed in new patch.
