Re: loading firmware while usermodehelper disabled.

To make the firmware caching easier I would propose one extra function
in addition to the aforemensioned get_firmware / put_firmware - a
find_firmware function to search the cache and return the appropriate
firmware blob. 

If the caller has a recount they have a pointer. If the caller can't work
out how to assign a 32bit value to a field in a struct please get them to
work on something less important than kernel code.
