Commit 7620fe91 ("ASoC: topology: fix memory leak in soc_tplg_dapm_widget_create") fixed a memory leak issue, but additional tests and KASAN reports show a use-after-free in soc-dapm. The widgets are created with a kmemdup operating on a template. The "name" string is also duplicated, but the "sname" string is not. As a result, when the template is freed after widget creation, its sname string is still used. Fix by explicitly duplicating the "sname" string, and freeing it when required. Signed-off-by:

Renesas sound card need to judge that whether it is using "TDM Split mode". To judge it and for other purpose, it has rsnd_parse_connect_simple() and rsnd_parse_connect_graph(), but these are using different judgement policy for TDM Split mode. It is pointless and confusable. This patch add new rsnd_parse_tdm_split_mode() and use common judgement policy for simple-card/audio-graph. Without this patch, CTU will be judged as TDM Split mode on audio-graph card. Signed-off-by:

The Spreadtrum DMA engine uses the link-list mode to support audio playback or capture, thus this patch adds audio DMA platform support for CPU DAI to trigger DMA link-list transfer. Signed-off-by:

struct snd_soc_dapm_route has been modified to be a dynamic object so that it can be used to save driver specific data while parsing topology and clean up driver-specific data during driver unloading. This patch makes the following changes to accomplish the above: 1. Set the dobj member of snd_soc_dapm_route during the SOC_TPLG_PASS_GRAPH pass of topology parsing. 2. Add the remove_route() routine that will be called while removing all dynamic objects from the component driver. Signed-off-by:

Add a new dobj type SND_SOC_DOBJ_GRAPH for dapm routes and add snd_soc_dobj member to struct snd_soc_dapm_route. This enables device drivers to save driver specific data pertaining to dapm routes and also be able to clean up the data when the driver module is unloaded. Also, reorder the snd_soc_dobj_type types to align with matching topology header types. Signed-off-by:

template.sname and template.name are only freed when an error occur. They should be freed in the success return case, too. Signed-off-by:

For some reason we test if the machine is passed as a parameter before fixing up the codec name. This is unnecessary, generates false positives in static analysis tools and done only in this machine driver, remove and adjust indentation. Reported-by:

Qualcomm WCD9335 Codec is a standalone Hi-Fi audio codec IC, It supports both I2S/I2C and SLIMbus audio interfaces. On slimbus interface it supports two data lanes; 16 Tx ports and 8 Rx ports. It has Seven DACs and nine dedicated interpolators, Seven (six audio ADCs, and one VBAT ADC), Multibutton headset control (MBHC), Active noise cancellation and Sidetone paths and processing. This patchset adds very basic support for playback and capture via the 9 interpolators and ADC respectively. Signed-off-by:
