Probably because I forgot to increment the version number.

No.

No. That's really pointless work and makes the linux-firmware package
even more complicated that it already is.
The firmware is getting installed and it's correct. Most times people
don't need to worry about which firmware they have, and if they do they
can consult the WHENCE file installed in /usr/share/doc/linux-firmware/.

Fedora is shipping at least one unnecessary firmware version compared to the kernels
used,
e.g. for
Intel® Centrino® Advanced-N 6205
IS required only iwlwifi-6000g2a-6.ucode - kernel 3.2+
and NOT iwlwifi-6000g2a-5.ucode - kernel 2.6.35+
iwlwifi-6000g2b-[56].ucode is a bit more complex case because it refers to four devices
i.e.
Intel® Centrino® Advanced-N 6230
Intel® Centrino® Wireless-N 1030
Intel® Centrino® Wireless-N 130
Intel® Centrino® Advanced-N 6235
IF I correctly understood
even the module itself "incorrectly" advertises some of the firmwares,
$ modinfo -F firmware iwlwifi
iwlwifi-100-5.ucode
iwlwifi-1000-5.ucode
iwlwifi-135-6.ucode
iwlwifi-105-6.ucode
iwlwifi-2030-6.ucode
iwlwifi-2000-6.ucode
iwlwifi-5150-2.ucode
iwlwifi-5000-5.ucode
iwlwifi-6000g2b-6.ucode
iwlwifi-6000g2a-5.ucode <-
iwlwifi-6050-5.ucode
iwlwifi-6000-4.ucode
iwlwifi-7265-8.ucode
iwlwifi-3160-8.ucode
iwlwifi-7260-8.ucode
iwlwifi-8000-8.ucode
Comment by you folks at Intel? :)
