Package: firmware-iwlwifi
Version: 20251111-1~bpo13+1
Severity: important

Dear Maintainer,
    I have a Starlabs Systems tablet, the StarLite mkV, with a N200 chipset.

Bluetooth has been unable to discover BLE devices for quite some time.
I believed it to be a kernel issue, and waited for an update.

The problem has appeared with several devices, for example a Logitech
Pebble M350s mouse.

Then I noticed this.

The firmware-iwlwifi package generates these symlinks in 
/lib/firmware/intel:

ibt-0040-2120.ddc -> ibt-0040-0041.ddc
ibt-0040-2120.sfi -> ibt-0040-1020.sfi

The second is wrong. It should be:

ibt-0040-2120.sfi -> ibt-0040-0041.sfi

Once I correct the symlink and reboot the tablet, the bluetooth
devices are discoved and paired without any problems.

I'm currently using firmware-iwlwifi/trixie-backports, but I've tried
with packages from stable and unstable, which are the same.

Thank you for everything you do for Debian.

René
