Andy Shevchenko authored
commit ec3decd2 upstream.

It's a repetition of the commit aa58a21a
  ("gpio: pca953x: disable regmap locking")
which states the following:

  This driver uses its own locking but regmap silently uses
  a mutex for all operations too. Add the option to disable
  locking to the regmap config struct.

Fixes: bcf41dc4 ("gpio: pca953x: fix handling of automatic address incrementing")

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.
