Quite frankly, I doubt you want a signal.
You will want to have some way to specify where the firmware files are. Right now we have "fw_path[]" which is hardcoded except for the first entry that can be set as a module parameter. But you'd probably want to expand on that, which implies some /sys or /proc interface.
And once you do that, wouldn't it make more sense to just make the "update the firmware path /proc/sys/kernel/fw_path file" make things re-search for firmware?
In other words, the interface has to be something *sensible*. Not some idiotic ad-hoc "send a signal" (of which that stupid original patch was just a very odd example).
