Subject: [PATCH AUTOSEL 4.19 012/258] wil6210: fix memory leak in wil_find_tx_bcast_2
Date: Mon, 28 Jan 2019 10:55:18 -0500 [thread overview]
Message-ID: <20190128155924.51521-12-sashal@kernel.org> (raw)
In-Reply-To: <20190128155924.51521-1-sashal@kernel.org>
From: Lior David <liord@codeaurora.org>
[ Upstream commit 664497400c89a4d40aee51bcf48bbd2e4dc71104 ]
A successful call to wil_tx_ring takes skb reference so
it will only be freed in wil_tx_complete. Consume the skb
in wil_find_tx_bcast_2 to prevent memory leak.
