ASoC: soc-pcm: tidyup soc_pcm_open() order
soc_pcm_open() operation order is not good. At first, soc_pcm_open() operation order is 1) CPU DAI startup 2) Component open 3) Codec DAI startup 4) rtd startup But here, 2) will call try_module_get() if component has module_get_upon_open flags. This means 1) CPU DAI startup will be operated *before* its module was loaded. DAI should be called *after* Component. Second, soc_pcm_close() operation order is 1) CPU DAI shutdown 2) Codec DAI shutdown 3) rtd shutdown 4) Component close soc_pcm_open() and soc_pcm_close() are paired function, but, its operation order is unbalance. This patch tidyup soc_pcm_open() order to Component -> rtd -> DAI. This is one of prepare for cleanup soc-pcm-open() Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Reviewed-by: Ranjani Sridharan <ranjani.sridharan@linux.intel.com> Link: https://lore.kernel.org/r/871rr3cext.wl-kuninori.morimoto.gx@renesas.com Signed-off-by: Mark Brown <broonie@kernel.org>
