Subject: [PATCH 5.18 300/879] nl80211: show SSID for P2P_GO interfaces

From: Johannes Berg <johannes.berg@...el.com>

[ Upstream commit a75971bc2b8453630e9f85e0beaa4da8db8277a3 ]

There's no real reason not to send the SSID to userspace
when it requests information about P2P_GO, it is, in that
respect, exactly the same as AP interfaces. Fix that.
