How can I install it as DKMS module on a unsupported distribution?

[sky96111]

I am using openSUSE which is unsupported in this repo. So I cannot install linux-surface-headers below.

#7

I refered to this issue and it says I need to install linux-surface-headers package which is not available in my distribution. So I installed kernel-default-devel (headers of my present kernel in use) to provide headers.

But I can't apply patch to my kernel for can't find file to patch. And I find that in /lib/modules/5.18.6.1-default/kernel/drivers/misc/mei/ actually doesn't exist hw-me-regs.h and pci-me.c two files.
So I ignored this step. I succeed in installing DKMS but iptsd cannot work with errors:

ERROR: ../src/control.c:139: Failed to open /dev/ipts/0: No such file or directory
ERROR: ../src/main.c:106: Failed to start IPTS: No such file or directory

Which step is wrong?
