In that case why don't we use async version and wait till the userspace is
availble and firmware is loaded. 

So request_firmware_nowait() seems to do the job, I have used in a device where
I call it in probe() so that not to slow booting and make firmware bloc availble
userpsace is availble.

Sounds too good, did I miss anything obvious for this case here?
