Artur Weber 508a550eec power: supply: max17042_battery: Fix SOC threshold calc w/ no current sense 
[ Upstream commit 3a3acf839b ]

Commit 223a3b8283 ("power: supply: max17042_battery: use VFSOC for
capacity when no rsns") made it so that capacity on systems without
current sensing would be read from VFSOC instead of RepSOC. However,
the SOC threshold calculation still read RepSOC to get the SOC
regardless of the current sensing option state.

Fix this by applying the same conditional to determine which register
should be read.

This also seems to be the intended behavior as per the datasheet - SOC
alert config value in MiscCFG on setups without current sensing is set
to a value of 0b11, indicating SOC alerts being generated based on
VFSOC, instead of 0b00 which indicates SOC alerts being generated based
on RepSOC.

This fixes an issue on the Galaxy S3/Midas boards, where the alert
interrupt would be constantly retriggered, causing high CPU usage
on idle (around ~12%-15%).

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.
