22f8716af9 ucm: complete dependency graphs for conflicting/supported device lists 
Modify verb_dev_list_check() to ensure all devices in a conflicting or
supported group reference each other. Previously, the function only
ensured bidirectional relationships. Now it ensures all devices in
the same group have complete dependency lists.

554efca497 ucm: implement ValueDefaults.BootCardGroup and define use 
We need a boot synchronization for multiple UCM cards where linking
is expected like AMD ACP or Intel AVS drivers. This method is
using a timestamp file which can be created and modified during
the boot process (e.g. from the alsactl tool).

The goal is to return a valid UCM configuration for standard
applications combining multiple ALSA cards into one UCM configuration
and cover the time window when all cards have not been probed yet.

41039b49ad snd_tlv_convert_to_dB: Fix mute handling for MINMAX_MUTE type
Some checks failed
Build alsa-lib / fedora_latest_build (push) Has been cancelled
Details
Build alsa-lib / ubuntu_last_build (push) Has been cancelled
Details 
Ensure the SND_CTL_TLV_DB_GAIN_MUTE value is returned when the calculated
gain equals the minimum dB value for the SNDRV_CTL_TLVT_DB_MINMAX_MUTE type.
The previous check based solely on the volume value could miss cases where
the linear calculation resulted in the minimum gain.
