[ Upstream commit b55d073e6501dc6077edaa945a6dad8ac5c8bbab ]
smatch complains that there is a buffer overflow and clang complains
'ret' is never read.
Smatch error:
drivers/power/supply/bq256xx_charger.c:1578 bq256xx_hw_init() error:
buffer overflow 'bq256xx_watchdog_time' 4 <= 4
Clang static checker:
Value stored to 'ret' is never read.
Add check for buffer overflow and error code from regmap_update_bits().
Fixes: 32e4978bb9 ("power: supply: bq256xx: Introduce the BQ256XX charger driver")

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.
