ASoC: Updates for v6.10

This is a very big update, in large part due to extensive work the Intel
people have been doing in their drivers though it's also been busy
elsewhere.  There's also a big overhaul of the DAPM documentation from
Luca Ceresoli arising from the work he did putting together his recent
ELC talk, and he also contributed a new tool for visualising the DAPM
state.

 - A new tool dapm-graph for visualising the DAPM state.
 - Substantial fixes and clarifications for the DAPM documentation.
 - Very large updates throughout the Intel audio drivers.
 - Cleanups of accessors for driver data, module labelling, and for
   constification.
 - Modernsation and cleanup work in the Mediatek drivers.
 - Several fixes and features for the DaVinci I2S driver.
 - New drivers for several AMD and Intel platforms, Nuvoton NAU8325,
   Rockchip RK3308 and Texas Instruments PCM6240.

ASoC: Use inline function for type safety in snd_soc_substream_to_rtd() 2024-05-02T03:57:25+00:00 Krzysztof Kozlowski krzysztof.kozlowski@linaro.org 2024-05-01T17:51:27+00:00 9723cab054d59d770cd1927f92fe315c26cc6a78 A common pattern in sound drivers is getting 'struct snd_soc_pcm_runtime' from 'struct snd_pcm_substream' opaque pointer private_data field with snd_soc_substream_to_rtd(). However 'private_data' appears in several other structures as well, including 'struct snd_compr_stream'. The field might not hold the same type for every structure, although seems the case at least for 'struct snd_compr_stream', so code can easily make a mistake by using macro for wrong structure passed as argument. Switch from macro to inline function, so such mistake will be build-time detectable.
