Just to double check, is there a macro set in SUSE that we can use here,
instead of defining here ourselves, like RHEL_RELEASE_CODE?

This line gives following checkpatch warning:

defined check is not required, since SLE_VERSION_CODE always defined [1].
It can be either:
a) (SLE_VERSION_CODE && SLE_VERSION_CODE == SLE_VERSION(12, 3, 0))
or directly check:
b) (SLE_VERSION_CODE == SLE_VERSION(12, 3, 0))
