Subject: [PATCH 09/49] pcm: Add snd_pcm_audio_tstamp_type_t constants

These are mostly a copy-paste from the kernel headers. But since functions
snd_pcm_audio_tstamp_config make use of these they should be added to the
public API as well.

The __snd_pcm_state() must return a valid state, not an error value
when the plugin callback is not defined. Use the first state
SND_PCM_STATE_OPEN - the other functions will return the error
code depending on this state.

Subject: [PATCH 22/49] pcm: plugin status - fix the return value (regression)

The snd_pcm_plugin_avail_update() error code in snd_pcm_plugin_status()
should not be reported to the caller. The state errors can be determined
using the state member in the status structure.

Fixes: 4f90392f07e ("pcm: fix the snd_pcm_plugin_status() avail and delay fields")

Subject: [PATCH 23/49] pcm: plugin status - revert the recent changes

It's no reason to sync the avail/delay fields using the mirrored
buffer pointers. The slave information must be valid.

The original report probably tries to fix something for
the specific plugin. Revert all changes.

Fixes: afe6ff3b33e ("pcm: plugin status - fix the return value (regression)")
Fixes: 4f90392f07e ("pcm: fix the snd_pcm_plugin_status() avail and delay fields")

Subject: [PATCH 25/49] pcm: plugin - optimize sync in snd_pcm_plugin_status()

Do hw_ptr sync only once after the status call. This avoids
double update.

Also, the application pointer must not change when
the status is called. Add assert() call for this condition.

Subject: [PATCH 31/49] pcm: plugin - fix status code for capture

The recent updates do not take in account the possible
calls for the capture stream. Fix the avail and delay
inconsistencies (and assert).

Subject: [PATCH 43/49] pcm: dmix/dshare - delay calculation fixes and cleanups

Unfortunately, we cannot use status->avail from slave, because this value
does not wrap to the buffer size and it may even overflow slave boundary
(endless run). We can use only hw_ptr from slave.

 condition code'

The whole SND_SOC_TPLG_TUPLE_TYPE_WORD condition part must be
commented out, otherwise the condition is always true.

Subject: [PATCH 45/49] pcm: direct: Fix the missing appl_ptr update

A snd_pcm_status() call for the direct plugins receives the status
from the slave PCM, but this doesn't contain a valid appl_ptr, since
the slave PCM for the direct plugins is in a free-wheel mode, hence
the appl_ptr is always zero.  This result in the inconsistent
status->appl_ptr and pcm->appl.ptr, hitting the recently introduced
assert() call.

Fix it by transferring the plugin's appl_ptr to the upper caller.

Subject: [PATCH 49/49] pcm: pcm_ioplug - fix the avail_update mmap capture
 copy issue

It seems that the commit "pcm: ioplug: Transfer all available data"
introduced new regressions (wrong memory access). The second issue
is that the avail_update in ioplug does not move appl_ptr nor hw_ptr,
so it's possible that the transfers may be repetitive.

This patch moves the transfer calls to mmap_begin callback where it
should be. The pointer wraps are handled by design now.
