Oh, I see.  I misunderstood you.  When you mentioned that you get the
message "firmware file not found", I thought you were getting that
message without the firmware name.  Indeed, the driver can print it
under some rare circumstances, but it's not the case here.

I should have asked you for the exact kernel log output before delving
into the sources and trying to guess what is happening.  That serves me
a lesson.

So you have a case of the firmware not loading at all.  I'm pretty sure
the problem lies outside the driver, and likely outside the kernel.
