We do not check kABI in Leap kernel branches like we do in SLE but as
openSUSE-15.2 shares the codebase (same tarball and patches) with SLE15-SP2,
the risk of breaking kABI in a way that would cause trouble is relatively low.
It would have to be a kABI breakage that would only manifest in parts of the
code which are built in openSUSE-15.2 but not SLE15-SP2.
