ASoC: soc-core: add for_each_rtd_components() and replace
ALSA SoC has for_each_rtdcom() which is link list for
rtd-component which is called as rtdcom. The relationship image is like below
rtdcom rtdcom rtdcom
component component component
rtd->component_list -> list -> list -> list ...
Here, the pointer get via normal link list is rtdcom,
Thus, current for_each loop is like below, and need to get
component via rtdcom->component
for_each_rtdcom(rtd, rtdcom) {
component = rtdcom->component;
...
}
but usually, user want to get pointer from for_each_xxx is component
directly, like below.
for_each_rtd_component(rtd, rtdcom, component) {
...
}
This patch expands list_for_each_entry manually, and enable to get
component directly from for_each macro.
Because of it, the macro becoming difficult to read,
but macro itself becoming useful.
