Lucas Rangit Magasweran 82f2d30570 ACPI: battery: remove redundant old_present check on insertion
On removal battery_present changes from 1 to 0 after calling
acpi_battery_get_status() and battery->update_time is set to 0
before returning.

On insertion battery_present changes from 0 to 1 after calling
acpi_battery_get_status() and acpi_battery_get_info() is called
because battery->update_time is 0.

The old_present condition is therefore redundant.

This was added in the commit below when there was a path without
sysfs that would skip getting the newly inserted battery info.

commit 50b178512b ("Newly inserted battery might differ from one
just removed, so update of battery info fields is required.")

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.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
