Can't resume from suspend because firmware is not found ?!?

Can't resume from suspend because firmware is not found ?!?

[Giuliano Pochini]

I tested suspend/resume on a laptop because I failed to make it work on my
G4 (grr!!). Suspend work, resume does not. From dmesg (below) it looks like
the soundcard driver is asked to resume before the ATA driver, thus is
cannot load the firmware. Am I overlooking something ?  Suggestions ?

You can't load the firmware file in resume phase because the system
isn't yet ready at this stage.  Either postpone it or keep the old
firmware and reuse it.

*sigh*
Ok, I'll try to find a workaround. I don't want to keep the firmware in
memory. Is there a way to know if resume is still in progress or when it is
possible to load the firmware ?  I could -as last resort- load the firmware
in the prepare callback.

Is it so high volume?  This is the easiest solution in general.

16KB to 150KB, depending on the card. Most cards need more than one
firmware and some of them have to reload the firmware during mormal
operation, so I also have to write a very simple cache manager. If
possible, I would prefer not to waste that memory.
