The per_pin->work might be still floating at the suspend, and this may hit the access to the hardware at an unexpected timing. Cancel the work properly at the suspend callback for avoiding the buggy access. Note that the bug doesn't trigger easily in the recent kernels since the work is queued only when the repoll count is set, and usually it's only at the resume callback, but it's still possible to hit in theory.
