The driver is doing a 64-bit divide, rather than using the proper
helpers, causing link errors on i386 allyesconfig builds:
x86_64-linux-ld: drivers/power/supply/intel_dc_ti_battery.o: in function `dc_ti_battery_get_voltage_and_current_now':
intel_dc_ti_battery.c:(.text+0x5c): undefined reference to `__udivdi3'
x86_64-linux-ld: intel_dc_ti_battery.c:(.text+0x96): undefined reference to `__udivdi3'
and while fixing that, fix the double rounding: keep the timing
difference in nanoseconds ('ktime'), and then just convert to usecs at
the end.
Not because the timing precision is likely to matter, but because doing
it right also makes the code simpler.

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 reStructuredText 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.
