This is somewhat off topic, but the fix in the description remains useful and is required to enable backlight brightness adjustment for the HP Stream 7 when running Debian 11 (Linux 5.10).
Example steps (to be run in an i386 environment, such as a debootstrap chroot jail):
apt install fakeroot devscripts
apt build-dep linux
apt source linux
cd linux-5.10.84/ # Change as needed
nano debian/config/kernelarch-x86/config
# Make the kernel configuration changes as in the description
debuild -b -uc -us
# Install linux-image-5.10.0-10-686-unsigned_5.10.84-1_i386.deb
