From: Ville Syrjälä <[email protected]> For whatever unknown reason the pmdemand code is using a custom 50 usec fast polling timeout instead of the normal 2 usec value. Switch to the standard value to get rid of the special case.
The eventual aim is to get rid of the fast vs. slow timeout entirely and switch over to poll_timeout_us().
