<code>
<code>
Fixes:
| ../../../alsa-lib-1.2.5/src/ucm/ucm_exec.c: In function 'find_exec':
| ../../../alsa-lib-1.2.5/src/ucm/ucm_exec.c:43:18: error: 'PATH_MAX' undeclared (first use in this function)
| 43 | char bin[PATH_MAX];
| | ^~~~~~~~
| ../../../alsa-lib-1.2.5/src/ucm/ucm_exec.c:43:18: note: each undeclared identifier is reported only once for each function it appears in

<code>
- ucm: fix out-of-array access in rval_device_lookup_init()
<code>

===Configuration===
- conf: snd_config_get_card() remove unused assignment
<code>
- conf: remove dead code in snd_config_get_card()
<code>
- conf: fix load_for_all_cards()
<code>
<code>
The 63f7745b commit is loading the driver specific configuration
multiple times which ends with the array merges (see the bug).

Introduce the loaded compound which traces the already loaded
driver configurations and skip the multiple load requests.</code>
==alsa-utils==
===Core===
- Release v1.2.5.1
<code>
===ALSA Control (alsactl)===
- utils.c: Include limits.h explicitly to fix build on musl
<code>
<code>
Fixes:
| ../../alsa-utils-1.2.5/alsactl/utils.c: In function 'snd_card_clean_cfgdir':
| ../../alsa-utils-1.2.5/alsactl/utils.c:309:19: error: 'PATH_MAX' undeclared (first use in this function)
| 309 | char path[PATH_MAX];
| | ^~~~~~~~
| ../../alsa-utils-1.2.5/alsactl/utils.c:309:19: note: each undeclared identifier is reported only once for each function it appears in</code>
- alsactl: load_state: Only delete config if one was loaded
<code>
<code>
If load_configuration fails with open_failed == true, load_state will
jump to the out label without config being initialized and pass this
uninitialized config value to snd_config_delete. This commit fixes this
issue by initializing config with NULL and checking if it is non-null
before invoking snd_config_delete.

BugLink: https://github.com/alsa-project/alsa-utils/issues/93</code>
- alsactl: load_state() - initialize config variable for the open_failed case
<code>
- alsactl: fix lock_fd unlock in load_configuration() - error path
<code>
- alsactl: state - fix ‘item’ may be used uninitialized gcc warning
<code>
- alsactl: check for error values from snd_config_get...()
<code>
- alsactl: init() - return error value from snd_card_iterator_sinit() call
<code>
- alsactl: return error value in dump_config_tree()
<code>
- alsactl: fix the nested iteration
<code>
<code>
There may be nested iterations for hw: card names.
Handle this card name in snd_card_iterator_sinit().

BugLink: https://github.com/alsa-project/alsa-lib/issues/142</code>
===Audio Transfer utility===
- axfer: fix wrong calloc() item size in allocate_containers()
<code>
===alsatplg (topology)===
- topology: fix few coverity detected defects
<code>
- topology: fix potential null pointer from strchr
<code>
<code>
This patch adds check to the return pointer from strchr,
because it may be null and cause segment fault, if component
is not properly constructed.</code>
===aplay/arecord===
- arecord: Inform users when 8-bit sampling is used on tty
<code>
<code>
When we reverted 0c5948e ("aplay: try to use 16-bit format to
increase capture quality"), we should also handle the original
problem somehow. This code shows a warning with a hint to
the right parameter.</code>
- Revert "aplay: try to use 16-bit format to increase capture quality"
<code>
<code>
This reverts commit 0c5948e98a6a8535c89b7bcab13017d7732181c6.

Link: https://github.com/alsa-project/alsa-utils/issues/96</code>
===aseqnet===
- added an option to aseqnet to optionally set the midi process name
<code>
<code>
This option allows to run multiple instances of aseqnet without having
to double check the assigned port number, since each one can get spawned
with a unique name.</code>
==alsa-ucm-conf==
===Configuration===
- tegra: Add UCM for Nvidia Tegra HDMI Audio
<code>
- HDA-Intel: the lookups are supported from syntax 4
<code>
- tegra: shuffle ASUS Google Nexus 7 files
<code>
<code>
BugLink: https://github.com/alsa-project/alsa-ucm-conf/pull/94</code>
- tegra: shuffle Acer Iconia Tab A500 files
<code>
<code>
