In 2.6, the semantics of calling yield() changed from "sleep for a bit" to "I really don't want to run for a while". This matches POSIX better, but there's a lot of drivers still using yield() when they mean cond_resched(), schedule() or even schedule_timeout().
For this driver cond_resched() seems to be a better alternative
Tested compile only
