this is a default behaviour of this and many other drivers.

in the end, there is no big deal in putting the firmware into the
initramfs. some distributions may work out of the box, some might
require a little tuning of an initramfs hook.

which leads me to my question: why are you absolutly against an
initramfs image? properly configured - and that is not a big deal
in current versions of mkinitramfs and current distributions - there
are few possibilities to break the setup.

if you require assistance, i can help.
