ALSA: compress: allow setting codec params after next track For gapless playback it is possible that each track can have different codec profile with same decoder, for example we have WMA album, we may have different tracks as WMA v9, WMA v10 and so on Or if DSP's like QDSP have abililty to switch decoders on single stream for each track, then this call could be used to set new codec parameters. Existing code does not allow to change this profile while doing gapless playback. Reuse existing SNDRV_COMPRESS_SET_PARAMS to set this new track params along some additional checks to enforce proper state machine. With this new changes now the user can call SNDRV_COMPRESS_SET_PARAMS anytime after setting next track and additional check in write should also ensure that params are set before writing new data.

ALSA: jack: implement software jack injection via debugfs This change adds audio jack injection feature through debugfs, with this feature, we could validate alsa userspace changes by injecting plugin or plugout events to the non-phantom audio jacks. With this change, the sound core will build the folders $debugfs_mount_dir/sound/cardN if SND_DEBUG and DEBUG_FS are enabled. And if users also enable the SND_JACK_INJECTION_DEBUG, the jack injection nodes will be built in the folder cardN like below: $tree $debugfs_mount_dir/sound $debugfs_mount_dir/sound ├── card0 │ ├── HDMI_DP_pcm_10_Jack │ │ ├── jackin_inject │ │ ├── kctl_id │ │ ├── mask_bits │ │ ├── status │ │ ├── sw_inject_enable │ │ └── type ... │ └── HDMI_DP_pcm_9_Jack │ ├── jackin_inject │ ├── kctl_id │ ├── mask_bits │ ├── status │ ├── sw_inject_enable │ └── type └── card1 ├── HDMI_DP_pcm_5_Jack │ ├── jackin_inject │ ├── kctl_id │ ├── mask_bits │ ├── status │ ├── sw_inject_enable │ └── type ... ├── Headphone_Jack │ ├── jackin_inject │ ├── kctl_id │ ├── mask_bits │ ├── status │ ├── sw_inject_enable │ └── type └── Headset_Mic_Jack ├── jackin_inject ├── kctl_id ├── mask_bits ├── status ├── sw_inject_enable └── type The nodes kctl_id, mask_bits, status and type are read-only, users could check jack or jack_kctl's information through them. The nodes sw_inject_enable and jackin_inject are directly used for injection. The sw_inject_enable is read-write, users could check if software injection is enabled or not on this jack, and users could echo 1 or 0 to enable or disable software injection on this jack. Once the injection is enabled, the jack will not change by hardware events anymore, once the injection is disabled, the jack will restore the last reported hardware events to the jack. The jackin_inject is write-only, if the injection is enabled, users could echo 1 or 0 to this node to inject plugin or plugout events to this jack. For the detailed usage information on these nodes, please refer to Documentation/sound/designs/jack-injection.rst.

docs: get rid of :c:type explicit declarations for structs The :c:type: foo only works properly with structs before Sphinx 3.x. On Sphinx 3.x, structs should now be declared using the .. c:struct, and referenced via :c:struct tag. As we now have the automarkup.py macro, that automatically convert: struct foo into cross-references, let's get rid of that, solving several warnings when building docs with Sphinx 3.x.
