From 9783e0407421a4dfc25e3a3001d0e0cff4236806 Mon Sep 17 00:00:00 2001 From: Rameshkumar Sundaram Date: Wed, 26 Jun 2024 08:12:57 +0530 Subject: [PATCH] wifi: ath12k: fix driver initialization for WoW unsupported devices Commit 4a3c212eee0e ("wifi: ath12k: add basic WoW functionalities") broke driver initialization, now mac registration is allowed only for devices that advertise WMI_TLV_SERVICE_WOW, but QCN9274 doesn't support WoW and hence mac registration is aborted and driver is de-initialized. Allow mac registration to proceed without WoW Support for devices that don't advertise WMI_TLV_SERVICE_WOW.
