Hugo Villeneuve 983f91e5f1 serial: sc16is7xx: declare SPR/TLR/XOFF2 register as volatile
SPR shares the same address space as TLR and XOFF2. If SPR or TLR were to
be used eventually, this could lead to incorrect read value from the cache.

Prevent this potential bug by declaring SPR/TLR/XOFF2 as volatile.

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 reStructuredText 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.
