From b40f97b91a3b167ab22c9e9f1ef00b1615ff01e9 Mon Sep 17 00:00:00 2001 From: Xie He Date: Thu, 31 Dec 2020 09:43:31 -0800 Subject: [PATCH] net: lapb: Decrease the refcount of "struct lapb_cb" in lapb_device_event In lapb_device_event, lapb_devtostruct is called to get a reference to an object of "struct lapb_cb". lapb_devtostruct increases the refcount of the object and returns a pointer to it. However, we didn't decrease the refcount after we finished using the pointer. This patch fixes this problem.
