commit35092c5819upstream. Add a cache parameter to bq27xxx_battery_current_and_status() so that it can optionally use cached flags instead of re-reading them itself. This is a preparation patch for making bq27xxx_battery_update() check the status and have it call power_supply_changed() on status changes.

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.
