Meanwhile, function is OK, my bluetooth headset still works fine.

Hum,

Analyzing /etc/bluetooth/main.conf as refered in RPM SPEC file as %{_sysconfdir}/bluetooth/*.conf :

In [Controller] section, there are these comments:

---BEGIN QUOTE-----

[Controller]
# The following values are used to load default adapter parameters.  BlueZ loads
# the values into the kernel before the adapter is powered if the kernel
# supports the MGMT_LOAD_DEFAULT_PARAMETERS command. If a value isn't provided,
# the kernel will be initialized to it's default value.  The actual value will
# vary based on the kernel version and thus aren't provided here.
# The Bluetooth Core Specification should be consulted for the meaning and valid
# domain of each of these values.

# BR/EDR Page scan activity configuration
#BRPageScanType=

#BRPageScanWindow=

# BR/EDR Inquiry scan activity configuration
#BRInquiryScanType=

#BRLinkSupervisionTimeout=

# specific values provided via the Load Connection Parameters interface
#LEMinConnectionInterval=
#LEMaxConnectionInterval=

--- END QUOTE-----------

All these values are not set. Comment above explicitly says: "If a value isn't provided,
the kernel will be initialized to it's default value.  The actual value will
vary based on the kernel version and thus aren't provided here.
The Bluetooth Core Specification should be consulted for the meaning and valid
domain of each of these values."

So if there is no value set, Kernel should set his default value and daemon should not complain by spamming dmesg.

Reported upstream

Comment 4 Aurelien Oudelet 2020-11-22 15:58:21 CET 
Ping. Still Bug still valid in current version.
Comment 5 Aurelien Oudelet 2020-11-30 11:35:41 CET 
This is fixes in Master on upstream git repo. No ETA to have a 5.56 release tag.
We should fix this by syncing upstream repo as this messes journal.
Comment 6 Aurelien Oudelet 2020-12-27 14:48:42 CET 
Ping Kernel and Drivers Maintainers.

BlueZ stack is updated upstream to disable such unnecessary warnings
See: Comment 3 and upstream issue link in Comment 2.

I am not packager but this seems easy to be done before releasing Mageia 8.
This will help Bugsquad when users could complain about something in Bluetooth.
