Here follows the equivalent experiment for the 5.2 series kernels --

[quote]
$ pwd
~/drivers/net/wireless/iwlwifi
$ grep "UCODE_API" * | grep define
iwl3945-base.c:#define IWL3945_UCODE_API "-1"
iwl4965-base.c:#define IWL4965_UCODE_API "-1"
$

In all of the three experiments, above, we have looked at the source
code. The type of kernel built from the source is, of course,
irrelevant.  ;-)

The sources used were -8.el5.src.rpm, -53.el5.src.rpm and -92.src.rpm,
respectively.
