2020-03-12ASoC: topology: Perform component check upfrontAmadeusz Sławiński
Function soc_tplg_dbytes_create(), calls soc_tplg_init_kcontrol() to perform additional driver specific initialization. While soc_tplg_init_kcontrol() ensures that component is valid before invoking ops->control_load, there is no such check at the end of soc_tplg_dbytes_create() where list_add() is used. Also in quite a few places, there is reference of tplg->comp->dapm or tplg->comp->card, without any checks for tplg->comp. In consequence of the above this may lead to referencing NULL pointer. This allows for removal of now unnecessary checks.

In case of ABI version mismatch, _manifest needs to be freed as it is just a copy of the original topology manifest. However, if a driver manifest handler is defined, that would get executed and the cleanup is never reached. Fix that by getting the return status of manifest() instead of returning directly.

2020-01-23ASoC: topology: fix soc_tplg_fe_link_create() - link->dobj initialization orderJaroslav Kysela
The code which checks the return value for snd_soc_add_dai_link() call in soc_tplg_fe_link_create() moved the snd_soc_add_dai_link() call before link->dobj members initialization. While it does not affect the latest kernels, the old soc-core.c code in the stable kernels is affected. The snd_soc_add_dai_link() function uses the link->dobj.type member to check, if the link structure is valid. Reorder the link->dobj initialization to make things work again. It's harmless for the recent code (and the structure should be properly initialized before other calls anyway). The problem is in stable linux-5.4.y since version 5.4.11 when the upstream commit 76d270364932 was applied.

2019-12-10ASoC: topology: Check return value for snd_soc_add_dai_link()Dragos Tarcatu
snd_soc_add_dai_link() might fail. This situation occurs for instance in a very specific use case where a PCM device and a Back End DAI link are given identical names in the topology. When this happens, soc_new_pcm_runtime() fails and then snd_soc_add_dai_link() returns -ENOMEM when called from soc_tplg_fe_link_create(). Because of that, the link will not get added into the card list, so any attempt to remove it later ends up in a panic. Fix that by checking the return status and free the memory in case of an error.

2019-04-08ASoC: topology: Use the correct dobj to free enum control values and textsRanjani Sridharan
The control values and texts of the enum kcontrol associated with a widget need to be freed when the widget is removed. However, both struct snd_soc_dapm_widget and struct soc_enum contain a dobj member, which resulted in a confusion. The existing code generates a null pointer dereference by attempting to free the values and texts from the dobj which belongs to the widget instead of the dobj belonging to the enum kcontrol. The suggested fix is to use the correct dobj member (se->dobj) of the enum kcontrol.

2019-02-04ASoC: topology: unload physical dai link in removeBard liao
soc_tplg_link_config() will find the physical dai link and call soc_tplg_dai_link_load() to load the BE dai link. Currently remove_link() is only used to remove the FE dai link which is created by the topology. The BE dai link cannot however be unloaded in snd_soc_tplg_component _remove(), which is problematic if anything needs to be released or reinitialized. This patch aligns the definitions of dynamic types with the existing UAPI and adds a new remove_backend_link() routine to unload the the BE dai link when snd_soc_tplg_component_remove() is invoked.
