[ Upstream commita7aaa80098] The pump_express_work which gets queued from an external_power_changed callback might be pending / running on remove() (or on probe failure). Add a devm action cancelling the work, to ensure that it is cancelled. Note the devm action is added before devm_power_supply_register(), making it run after devm unregisters the power_supply, so that the work cannot be queued anymore (this is also why a devm action is used for this).

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.
