2020-05-30ASoC: soc-card: add probed bit field to snd_soc_cardKuninori Morimoto
We already have bit field to control snd_soc_card. Let's add "probed" field on it instead of local variable. One note here is that soc_cleanup_card_resources() will be called as (A) formal cleanup or as (B) error handling, thus, it needs to distinguish these. In (A) case, card will have "instantiated" flag if all probe callback functions were called without error. Thus, snd_soc_unbind_card() is using it to judging card was probed. But this this patch removes it, because it is no longer needed.

2020-05-27ASoC: dapm: Move dai_link widgets to runtime to fix use after freeCharles Keepax
The newly added CODEC to CODEC DAI link widget pointers in snd_soc_dai_link are better placed in snd_soc_pcm_runtime. snd_soc_dai_link is really intended for static configuration of the DAI, and the runtime for dynamic data. The snd_soc_dai_link structures are not destroyed if the card is unbound. The widgets are cleared up on unbind, however if the card is rebound as the snd_soc_dai_link structures are reused these pointers will be left at their old values, causing access to freed memory.

2020-05-08ASoC: soc-core: Replace zero-length array with flexible-arrayGustavo A. R. Silva
The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] sizeof(flexible-array-member) triggers a warning because flexible array members have incomplete type[1]. There are some instances of code in which the sizeof operator is being incorrectly/erroneously applied to zero-length arrays and the result is zero. Such instances may be hiding some bugs. So, this work (flexible-array member conversions) will also help to get completely rid of those sorts of issues. This issue was found with the help of Coccinelle.

2020-04-14ASoC: dapm: Fix regression introducing multiple copies of DAI widgetsCharles Keepax
Refactoring was done to factor out the linking of DAI widgets into a helper function, dapm_add_valid_dai_widget. However when this was done, a regression was introduced for CODEC to CODEC links. It was over looked that the playback and capture variables persisted across all CODEC DAIs being processed, which ensured that the special DAI widget that is added for CODEC to CODEC links was only created once. This bug causes kernel panics during DAPM shutdown. To stick with the spirit of the original refactoring whilst fixing the issue, variables to hold the DAI widgets are added to snd_soc_dai_link. Furthermore the dapm_add_valid_dai_widget function is renamed to dapm_connect_dai_pair, the function only adds DAI widgets in the CODEC to CODEC case and its primary job is to add routes connecting two DAI widgets, making the original name quite misleading.

2020-03-20ASoC: soc-core: Merge CPU/Codec DAIsKuninori Morimoto

ASoC core supports multiple codec DAIs but supports only a CPU DAI. To support multiple cpu DAIs, add cpu_dai and num_cpu_dai in snd_soc_dai_link and snd_soc_pcm_runtime structures similar to support for codec_dai. This is intended as a preparatory patch to eventually support the unification of the Codec and CPU DAI. Inline with multiple codec DAI approach, add support to allocate, init, bind and probe multiple cpu_dai on init if driver specifies that. Also add support to loop over multiple cpu_dai during suspend and resume. This is intended as a preparatory patch to eventually unify the CPU and Codec DAI into DAI components.

2019-12-10ASoC: soc-core: rename snd_soc_add_dai_link() to snd_soc_add_pcm_runtime()Kuninori Morimoto
Now soc-core and soc-topology is using snd_soc_add_dai_link(). The abstract of this function is "create pcm_runtime from dai_link information and connect it to card". Thus, "add dai_link" is wrong/confusable naming. This patch renames function name.

2019-12-10ASoC: soc-core: remove dai_link_listKuninori Morimoto
ASoC is using many lists. Now, used dai_link is listed to card as dai_link_list. [card]->[dai_link]->[dai_link]->... BTW, this "dai_link" is used to create "rtd". And this rtd is listed to card as rtd_list. [card]->[rtd]->[rtd]->... Here, each rtd has dai_link. This means, we can track all dai_link via rtd list. This patch removes card dai_link_list, and uses rtd_list instead of it.

2019-12-04ASoC: core: Init pcm runtime work early to avoid warningsCurtis Malainey
There are cases where we fail before we reach soc_new_pcm which would init the workqueue. When we fail we attempt to flush the queue which generates warnings from the workqueue subsystem when we have not inited the queue. Solution is to use a proxy function to get around this issue.

2019-11-05ASoC: soc-core: don't call snd_soc_dapm_new_dai_widgets() at ↵Kuninori Morimoto
snd_soc_register_dai() ALSA SoC has 2 functions. snd_soc_register_dai() is used from topology snd_soc_register_dais() is used from snd_soc_add_component() In general, people think like _dai() is called from _dais() with for loop. But in reality, these are very similar but different implementation. We shouldn't have duplicated and confusing implementation. snd_soc_register_dai() is now used from topology. But to reduce duplicated code, it should be used from _dais(), too. Because of topology side specific reason, it is calling snd_soc_dapm_new_dai_widgets(), but it is not needed _dais() side. This patch factorizes snd_soc_register_dai() to topology / _dais() common part, and topology specific part. And do topology specific part at soc-topology.

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.
