Subject: cfg80211: clear wep keys after disconnection
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=f6bfc88f14cc176d9dae7739ab19a3e59b101f57;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

cfg80211: clear wep keys after disconnection

[ Upstream commit 3027a8e799b20fc922496a12f8ad2f9f36a8a696 ]

When a low level driver calls cfg80211_disconnected(), wep keys are
not cleared. As a result, following connection requests will fail
since cfg80211 internal state shows a connection is still in progress.

Fix this by clearing the wep keys when disconnecting.
