CVE: CVE-2023-33288

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=2b346876b93168541a45551d5f9abd1d26102e89

--------------------------------

[ Upstream commit 47c29d69 ]

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
