Subject: ath10k_pci logs errors about missing pre-cal and cal firmware on a
 laptop

Dear Linux folks,


Onn the Dell XPS 13 9360 with Debian sid/unstable, Linux 6.5.10 logs the 
error below:

     $ sudo dmesg | grep -e "DMI:" -e "Linux version" -e microcode

As it’s logged with error level, I’d like to address the ath10k_pci 
errors, but I am unable to find the firmware in the Linux firmware 
archive [1].

What can I do about this?


Kind regards,

Paul
