I don't think so. Drivers are not supposed to know about bootup or
initramfs issues. If they want, they can disable the timeout, and wait
for userspace to handle the request any time later, but they should
not try to be smart here.
Currently, firmware requests are cancelled if the firmware isn't
found, but that's a userspace issue, and nothing the kernel should try
to work around.
I can not agree more. I prefer to keep my driver happily unaware. I will
just take the firmware loading away from the module init path and stop
worrying about userspace issues ;-)
