The following patch should be considered instead, as it removes completely
callers of sleep_on*().

Thanks,
Nish

Use wait_event_interruptible_timeout() instead of the deprecated
interruptible_sleep_on_timeout(). The existing code is complicated in the
conditional and so is the new code. Also replace sleep_on_timeout() with direct
wait-queue usage. Patch is compile-tested.
