If we encounter an error on the DSP side whilst user-space is waiting on the poll we should call snd_compr_fragment_elapsed, although data is not actually available we want to wake user-space such that the error can be propagated out quickly. Additionally some versions of the DSP firmware are not super consistent about actually generating an IRQ if they encounter an error, as such we will check the DSP error status every time we run out of available data as well, to ensure we catch it.
