Replace the #include of <linux/mod_devicetable.h> by the more specific
<linux/device-id/*.h> where applicable. For most cases the include
can be dropped completely, only a few drivers need one or two headers
added.

When q6apm_free_fragments() is called it frees rx_data.buf/tx_data.buf
and sets them to NULL under graph->lock. A late DSP buffer-done response
can race with this: graph_callback() passes the !graph->ar_graph guard
(not yet NULL), acquires the lock, but then dereferences a now-NULL buf
pointer to read buf[token].phys, crashing at virtual address 0x10.

Add a NULL check for buf inside the mutex-protected section in both the
write-done (DATA_CMD_RSP_WR_SH_MEM_EP_DATA_BUFFER_DONE_V2) and
read-done (DATA_CMD_RSP_RD_SH_MEM_EP_DATA_BUFFER_V2) handlers and bail
out cleanly if buffers have already been freed.

This problem is only shown up recently while apr bus was updated to
process the commands per service rather from single global queue.

Cássio Gabriel <cassiogabrielcontato@gmail.com> says:

Some ASoC drivers still manually release child OF nodes
when leaving child-node iteration loops early.

Convert these focused cases to scoped OF node cleanup
so early returns and normal loop exits keep the same node
lifetime handling without explicit of_node_put() calls.

- Patch 1 updates qcom_snd_parse_of() to use
  for_each_available_child_of_node_scoped() for link nodes and
  __free(device_node) for temporary cpu/platform/codec child nodes.
- Patch 2 updates fsl_qmc_audio to use
  for_each_available_child_of_node_scoped() for DAI child-node parsing.
- Patch 3 updates cygnus-ssp to use
  for_each_available_child_of_node_scoped() for SSP child-node parsing.

qcom_snd_parse_of() manually drops the link child node and the
cpu/platform/codec child nodes on error paths and at the end of each
iteration.

Use for_each_available_child_of_node_scoped() for the link node and
__free(device_node) for the named child nodes. This keeps the existing
ownership rules for DAI component phandle references, while removing the
manual cleanup labels from a path that has previously needed OF refcount
fixes.

Wire q6apm-dai to use push-pull shared memory graphs.

For push-pull graphs, configure the circular buffer and position buffer,
register watermark events, and use watermark notifications to report PCM
period elapsed. Skip legacy fragment queueing and ACK handling because the
DSP reads/writes directly from the shared circular buffer.

Push-pull shared memory modules can report watermark events when the DSP
read/write index reaches configured circular buffer levels.

Add support for registering watermark levels with the shared memory module
and route the resulting module event to q6apm clients using a new
APM_CLIENT_EVENT_WATERMARK_EVENT event.

Push-pull graphs use MODULE_ID_SH_MEM_PULL_MODE for playback and
MODULE_ID_SH_MEM_PUSH_MODE for capture instead of the legacy WR/RD shared
memory endpoints. Detect these modules when opening the graph, cache their
instance ID in graph->shm_iid, and use them for media format setup.

Also add support for mapping the position buffer required by push-pull mode
and configuring the DSP with circular buffer and position buffer addresses.

The shared memory module instance ID is now cached in graph->shm_iid when
the graph is opened. The old WR/RD shared memory IID helper functions are
no longer used.

Return errors from audioreach_set_media_format() to ensure callers are
notified when media format setup fails.

This could hide failures while programming media format parameters for
individual modules and allow graph setup to continue with incomplete
configuration.
