soc_get_playback_capture() (A) is using rtd->dai_link->xxx everywhere. Because of that, 1 line is unnecessarily long and not readable.
(A) static int soc_get_playback_capture(...) { if (rtd->dai_link->dynamic ...) { ^^^^^^^^^^^^^ ... } else { int cpu_capture = rtd->dai_link->c2c_params ? ^^^^^^^^^^^^^ ... }
if (rtd->dai_link->playback_only) { ^^^^^^^^^^^^^ ... } ... }
This patch uses variable "dai_link" to be clear code. Nothing changes the meanings.
