I don't have a perfect insight in the SUSE distro variants and their
kernel versions.

But the error above seems we have others that are > 5.3.18 but at the
same time not have the backport.

I'll try to create a v3, but do we have anyone from Suse to usually
directly ping for feedback on this?

I outlined that in the commit message already, and since the RH8.3
check above was added without inline comment I kept the same style.
With the updated v3 it will be readable from the code as I'll try
  (SLE_VERSION_CODE >= SLE_VERSION(15, 3, 0)

I'll submit the v3 after it has passed my test builds which include
- SLE_12_SP4
- SLE_15
- openSUSE_Factory_ARM
- openSUSE_Leap_15.2
- openSUSE_Leap_42.3
- openSUSE_Tumbleweed

And of those SLE_15 was the one affected without this fix due to their
new new kernel.
