From d99975c4953eb79e389d4630e848435c700e2dfc Mon Sep 17 00:00:00 2001 From: Wen Gong Date: Wed, 1 Feb 2023 01:53:13 -0500 Subject: wifi: cfg80211: call reg_notifier for self managed wiphy from driver hint Currently the regulatory driver does not call the regulatory callback reg_notifier for self managed wiphys. Sometimes driver needs cfg80211 to calculate the info of ieee80211_channel such as flags and power, and driver needs to get the info of ieee80211_channel after hint of driver, but driver does not know when calculation of the info of ieee80211_channel become finished, so add notify to driver in reg_process_self_managed_hint() from cfg80211 is a good way, then driver could get the correct info in callback of reg_notifier.
