[PATCH AUTOSEL 5.19 082/105] Bluetooth: use memset avoid memory leaks

From: Sasha Levin
Date: Thu Aug 11 2022 - 11:47:49 EST


From: Xiaohui Zhang <xiaohuizhang@xxxxxxxxxx>

[ 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
