Nothing wrong except it makes kernel larger while gives _absolutely_ no
benefit to end users. Regardless bus code prints core name or not it
(core name) have absolutely no impact on driver matching.
Imagine yourself an end-user who haven't got his 80211 core matched with
driver and therefore he haven't got WiFi working.
If bus driver code outputs
Core X: id 0x812, rev. 8, vendor 0x4BF
you (as end user) will look where is 0x4BF/0x812 driver supporting
rev.8.
But if bus driver code outputs
Core X: MAC 802.11 (core id 0x812, rev. 8, vendor 0x4BF)
you (as end user) empowered with MAC 802.11 name knowledge will still
look where is 0x4BF/0x812 driver supporting rev.8.
Really, there will be more and more core codes/types/name. Why hardcode
those into kernel for some e. g. memory-constraint system while you
still can (and in most cases also will) have them in dedicated drivers?
Btw, have you ever suffered hardly from PCI naming devices xxxx.xx.xx.x
but not "Network device" ?
Have nice day,
George
