From bf7a282d56a0765eea68faca8d743f1108fbce66 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?=C3=8D=C3=B1igo=20Huguet?= Date: Wed, 24 May 2023 15:00:36 +0200 Subject: [PATCH 105/142] wifi: rtw89: coex: Packet traffic arbitration hardware owner monitor MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Bugzilla: https://bugzilla.redhat.com/2207499 commit ae4e1adbb1be65cadde793239a39fa947a3ff828 Author: Ching-Te Ku Date: Fri Jan 6 20:08:42 2023 +0800 wifi: rtw89: coex: Packet traffic arbitration hardware owner monitor Because the difference of the hardware design, RTL8852C can not get the PTA owner by the same method with RTL8852B, RTL8852A. Modify the get owner API and related logic.
