I just got a new Laptop (Asus Expertbook P5405) with Intel Lunar Lake SoC and Intel Wi-Fi adapter.
Here is the device info from `lspci -nnk`:
```
00:14.3 Network controller [0280]: Intel Corporation Device [8086:a840] (rev 10)
DeviceName: WLAN
Subsystem: Intel Corporation Device [8086:0094]
Kernel modules: iwlwifi
```
The iwlwifi driver in Linux is looking for a firmware that I cannot find anywhere. dmesg output:
```
$ sudo dmesg | grep iwlwifi
[ 4.039116] iwlwifi 0000:00:14.3: enabling device (0000 -> 0002)
[ 4.042241] iwlwifi 0000:00:14.3: Detected crf-id 0x400410, cnv-id 0x1080900 wfpm id 0x80005b20

[ 4.044805] iwlwifi 0000:00:14.3: maximum version supported: iwlwifi-bz-b0-gf-a0-93
[ 4.044805] iwlwifi 0000:00:14.3: check git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git
```
When are you planning to release the firmware for these devices? Or is this error message a red herring and the device is not yet supported by the iwlwifi kernel module at all?
I have tested with Linux kernel 6.11.2 and 6.12-rc7 (I am compiling 6.12 right now as it just has been released).

I suppose this can be marked as solved. The firmware showed up in the linux-firmware git [1] yesterday, and with a kernel built from the wireless-next tree [2] I now have working Wi-Fi on my laptop.

(note that we need IWL_BZ_UCODE_API_MAX >= 94 in drivers/net/wireless/intel/iwlwifi/cfg/bz.c)
