[ Upstream commit49d8a56064] Before freeing struct sco_conn, all delayed timeout work should be cancelled. Otherwise, sco_sock_timeout could potentially use the sco_conn after it has been freed. Additionally, sco_conn.timeout_work should be initialized when the connection is allocated, not when the channel is added. This is because an sco_conn can create channels with multiple sockets over its lifetime, which happens if sockets are released but the connection isn't deleted.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
