If the firmware file name ever changes, then you'll have to find and 
modify it in 2 places.

I don't really have a strong preference, but I would like to see 
MODULE_FIRMWARE() used so I can cut down on the number of false 
positives as I go through the kernel firmware directory and the 
linux-firmware package to filter out unused files using modinfo.
