Bluetooth: cmtp: Fix deadlock in session deletion
Commit fada4ac339 introduced the usage of kthread API. kthread_stop is a blocking function which returns only when the thread exits. In this case, the thread can't exit because it's waiting for the write lock, which is being held by cmtp_del_connection() which is waiting for the thread to exit -- deadlock. Revert cmtp_reset_ctr to its original behavior: non-blocking signalling for the session to terminate. Signed-off-by: Peter Hurley <peter@hurleysoftware.com> Signed-off-by: Gustavo F.
