Debian: Possible missing firmware

If you encounter issue like the following, you need to download/update firmware files.
W: Possible missing firmware /lib/firmware/i915
The script below recursively downloads all available firmware for i915, (as example) copies files related to kernel 5.19 and updates initramfs which should now be without warnings.
wget -r --no-parent https://anduin.linuxfromscratch.org/sources/linux-firmware/i915/

# kernel 5.19
find -name *.bin | grep 2_16 | xargs -I {} cp {} /lib/firmware/i915/
find -name *.bin | grep 70 | xargs -I {} cp {} /lib/firmware/i915/

sudo update-initramfs -c -k all
