## Overview

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

iio: light: gp2ap020a00f: drain irq_work after free_irq

The threaded IRQ handler queues data->work through irq_work_queue() so
the trigger is polled from a per-CPU context.  free_irq() does not flush
an irq_work the handler already queued, so after gp2ap020a00f_remove()
returns that work may still run and call iio_trigger_poll() on data->trig,
which the devm cleanup has already freed, causing a use-after-free.

Add irq_work_sync(&data->work) after free_irq() in remove() and in the
probe error path, mirroring commit 78601726d4a5 ("iio: trigger: sysfs:
fix use-after-free on remove").

Found by an in-house static analysis tool, confirmed by manual review.
