"rtd" is handled by soc_xxx_pcm_runtime(), and "rtd->dev" is handled by soc_rtd_xxx().
There is no reason to separate these, and it makes code complex. We can free these in the same time.
Here soc_rtd_free() (A) which frees rtd->dev is called from soc_remove_link_dais() many times (1). Then, it is using dev_registered flags to avoid multi kfree() (2). This is no longer needed if we can merge these functions.
static void soc_remove_link_dais(...) { ...
(1) for_each_comp_order(order) { (1) for_each_card_rtds(card, rtd) {
(A) soc_rtd_free(rtd); ... } } }
(A) static void soc_rtd_free(...) { (2) if (rtd->dev_registered) { /* we don't need to call kfree() for rtd->dev */ device_unregister(rtd->dev); (2) rtd->dev_registered = 0; } }
This patch merges soc_rtd_free() into soc_free_pcm_runtime().

Morimoto-san,
I think it is useful to keep this comment when you move soc_rtd_free() to soc_free_pcm_runtime().
Thanks, Ranjani
