Haibo Chen a941e6d5ba gpio: pca953x: use the correct range when do regmap sync 
[ Upstream commit 2abc17a93867dc816f0ed9d32021dda8078e7330 ]

regmap will sync a range of registers, here use the correct range
to make sure the sync do not touch other unexpected registers.

Find on pca9557pw on imx8qxp/dxl evk board, this device support
8 pin, so only need one register(8 bits) to cover all the 8 pins's
property setting. But when sync the output, we find it actually
update two registers, output register and the following register.

Fixes: b765743005 ("gpio: pca953x: Restore registers after suspend/resume cycle")
Fixes: ec82d1eba3 ("gpio: pca953x: Zap ad-hoc reg_output cache")
Fixes: 0f25fda840 ("gpio: pca953x: Zap ad-hoc reg_direction cache")

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.
