CVE-2026-89468

power: supply: lp8788-charger: fix use-after-free on remove

In the Linux kernel, the following vulnerability has been resolved:

power: supply: lp8788-charger: fix use-after-free on remove

lp8788_charger_remove() flushes charger_work before unregistering the
IRQs. An IRQ thread can queue charger_work after flush_work() has
returned. The work can then run after devres frees pchg and dereference
it in lp8788_charger_event().

Unregister the IRQs first. free_irq() waits for any running threaded
handler, so no handler can queue more work afterwards. Then use
cancel_work_sync() to cancel pending work or wait for running work to
finish.

This issue was found by an in-house static analysis tool.
