ASoC: fsl: fsl_dma: remove snd_pcm_ops
snd_pcm_ops is no longer needed. Let's use component driver callback. Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Link: https://lore.kernel.org/r/87bluz90d1.wl-kuninori.morimoto.gx@renesas.com Signed-off-by: Mark Brown <broonie@kernel.org>
