Desmond Cheong Zhi Xi 27c24fda62 Bluetooth: switch to lock_sock in SCO
Since sco_sock_timeout is now scheduled using delayed work, it is no
longer run in SOFTIRQ context. Hence bh_lock_sock is no longer
necessary in SCO to synchronise between user contexts and SOFTIRQ
processing.

As such, calls to bh_lock_sock should be replaced with lock_sock to
synchronize with other concurrent processes that use lock_sock.

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.
