Sven Van Asbroeck d12fbc55c1 power: supply: ltc2941-battery-gauge: fix use-after-free 
commit a60ec78d30 upstream.

This driver's remove path calls cancel_delayed_work().
However, that function does not wait until the work function
finishes. This could mean that the work function is still
running after the driver's remove function has finished,
which would result in a use-after-free.

Fix by calling cancel_delayed_work_sync(), which ensures that
that the work is properly cancelled, no longer running, and
unable to re-schedule itself.

This issue was detected with the help of Coccinelle.

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.
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.
