3.16.44-rc1 review patch. If anyone has any objections, please let me know. ------------------ From: Nicholas Mc Guire <hofrat@xxxxxxxxx> commit 4a312c9c825adf74c0026c98fed4ab59ce190863 upstream. ulseep_range() uses hrtimers and provides no advantage over msleep() for larger delays. Fix up the 70/80ms delays here passing the "min" value to msleep(). This reduces the load on the hrtimer subsystem.
