On all newer bq27xxx ICs, the AveragePower register contains a signed value; in addition to handling the raw value as unsigned, the driver code also didn't convert it to µW as expected. At least for the BQ28Z610, the reference manual incorrectly states that the value is in units of 1mW and not 10mW. I have no way of knowing whether the manuals of other supported ICs contain the same error, or if there are models that actually use 1mW. At least, the new code shouldn't be *less* correct than the old version for any device. power_avg is removed from the cache structure, se we don't have to extend it to store both a signed value and an error code. Always getting an up-to-date value may be desirable anyways, as it avoids inconsistent current and power readings when switching between charging and discharging.

README
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.
