I still don't like too much the "not possible to sleep for long time"
expression.
Maybe change it to "should sleep for as small periods as possible since
it increases boot time of device drivers requesting firmware in their
->probe() methods."
This way you explain exactly why - this way people who don't know the
code will know exactly what the comments mean and what the intention
was.
Thanks.
