Subject: [PATCH 05/15] cfg80211: don't WARN if a self-managed device doesn't have a regdom
Date: Fri,  9 Apr 2021 12:40:18 +0300
Message-ID: <iwlwifi.20210409123755.ba2ea961f4ae.I8fde32d3196e860efa3b4ec464c42194195b42ec@changeid> (raw)
In-Reply-To: <[e-mail]>

From: Emmanuel Grumbach <[e-mail]>

This can happen if it booted in RF-Kill and didn't have a
chance to get its regulatory domain yet.
This can happen for example if hostapd is started on a device
that is blocked by RF-Kill.
