From d123172175db84a65bf66245bfa15aaabaa361a9 Mon Sep 17 00:00:00 2001 From: Igor Mitsyanko Date: Wed, 20 Mar 2019 10:03:48 +0000 Subject: [PATCH] qtnfmac: make regulatory notifier work on per-phy basis Wireless core calls regulatory notifier for each wiphy and it only guarantees that bands info is updated for this particular wiphy prior to calling a notifier. Hence updating all wiphy which belong to driver in a single notifier callback is redundant and incorrect.
