[PATCH AUTOSEL 5.18 74/93] Bluetooth: use memset avoid memory leaks

From: Sasha Levin <sashal@kernel.org>
Date: 2022-08-11 16:09:28
Also in: linux-bluetooth, lkml, stable
Subsystem: bluetooth subsystem, the rest · Maintainers: Marcel Holtmann, Luiz Augusto von Dentz, Linus Torvalds

From: Xiaohui Zhang <redacted>

[ Upstream commit a5133fe87ed827ce94084eecb7830a6d451ef55c ]

Similar to the handling of l2cap_ecred_connect in commit d3715b2333e9
("Bluetooth: use memset avoid memory leaks"), we thought a patch
might be needed here as well.

Use memset to initialize structs to prevent memory leaks
in l2cap_le_connect
