CVE-2026-89469

power: supply: lp8727: fix use-after-free in lp8727_release_irq()

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

power: supply: lp8727: fix use-after-free in lp8727_release_irq()

lp8727_isr_func(), the threaded IRQ handler, is the only caller that arms
pchg->work via schedule_delayed_work().  lp8727_release_irq() currently
cancels the work before freeing the IRQ, so an IRQ delivered in between
can re-arm the work through the threaded handler.  After .remove returns
the devm layer frees pchg while lp8727_delayed_func() may still run and
dereference it.

Free the IRQ first so the threaded handler is quiesced and can no longer
queue work, then cancel the delayed work to drain the final generation.

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