Subject: [PATCH 6.1.y] Revert "wifi: cfg80211: stop NAN and P2P in cfg80211_leave"
Date: Tue, 14 Apr 2026 10:16:33 +0800 [thread overview]
Message-ID: <20260414021633.2765982-1-guocai.he.cn@windriver.com> (raw)
From: Guocai He <guocai.he.cn@windriver.com>
This reverts commit 0c4f1c02d27a880b10b58c63f574f13bed4f711d which is commit
e1696c8bd0056bc1a5f7766f58ac333adc203e8a upstream.
The reverted patch introduced a deadlock. The locking situation in mainline is
totally different, so it is incorrect to directly backport the commit from mainline.
