Zheng Wang 4a1b82ee33 power: supply: bq24190: Fix use after free bug in bq24190_remove due to race condition
[ Upstream commit 47c29d69212911f50bdcdd0564b5999a559010d4 ]

In bq24190_probe, &bdi->input_current_limit_work is bound
with bq24190_input_current_limit_work. When external power
changed, it will call bq24190_charger_external_power_changed
 to start the work.

If we remove the module which will call bq24190_remove to make
cleanup, there may be a unfinished work. The possible
sequence is as follows:

CPU0                  CPUc1

                    |bq24190_input_current_limit_work
bq24190_remove      |
power_supply_unregister  |
device_unregister   |
power_supply_dev_release|
kfree(psy)          |
                    |
                    | power_supply_get_property_from_supplier
                    |   //use

Fix it by finishing the work before cleanup in the bq24190_remove

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.

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.
