[PATCH 6.6.y] Revert "wifi: cfg80211: stop NAN and P2P in cfg80211_leave"
Posted by guocai.he.cn@windriver.com 8 hours ago
From: Guocai He <guocai.he.cn@windriver.com>

This reverts commit 4d7a05da767e5cbcf4db511b9289d7ebd380dc56 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.
