Message-Id: <20240826-mwifiex-cleanup-1-v1-1-56e6f8e056ec@pengutronix.de> Date: Mon, 26 Aug 2024 13:01:22 +0200 From: Sascha Hauer <s.hauer@...gutronix.de> To: Brian Norris <briannorris@...omium.org>, Francesco Dolcini <francesco@...cini.it>, Kalle Valo <kvalo@...nel.org> Cc: linux-wireless@...r.kernel.org, linux-kernel@...r.kernel.org, Sascha Hauer <s.hauer@...gutronix.de> Subject: [PATCH 01/12] wifi: mwifiex: add missing locking cfg80211_rx_assoc_resp() and cfg80211_rx_mlme_mgmt() need to be called with the wiphy locked, so lock it before calling these functions.
