I believe the iwlxxx drivers were disabled (or absent) in the <= 5.2
kernels. One exception is the centosplus kernel.  Both iwl3945 and
iwl4965 are enabled in 5.2:

grep "UCODE_API" * | grep define
iwl3945-base.c:#define IWL3945_UCODE_API "-1"
iwl4965-base.c:#define IWL4965_UCODE_API "-1"

(from -92.1.22 cplus kernel)
