Nothing cancels this work\nbefore iio_trig_release() frees the trigger, so a worker armed by the\nlast in-flight IRQ can outlive the free and touch freed memory.\n\nCancel it at the top of iio_trig_release(), which every free path\nreaches through the device core's final put_device().\n\nFound by an in-house static analysis tool."
