Subject: drivers/staging/wlan-ng/p80211conv.c: fixed a potential memory leak
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=b5956dd26f848086af7413d8d089b4ab41ab341d;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

drivers/staging/wlan-ng/p80211conv.c: fixed a potential memory leak

Fixed a potential memory leak inside skb_ether_to_p80211()
	When the wep_encrypt() fails  the code return 2 directly
	Which causes the p80211_wep->data dangling

Add a kfree statement to reclaim that memory allocated
