From c9def7c85675608922263630ed3c84e66e6328eb Mon Sep 17 00:00:00 2001 From: Nicholas Mc Guire Date: Mon, 23 Jan 2017 15:00:40 -0800 Subject: [PATCH] UPSTREAM: usb: dwc2: host: use msleep() for long delay ulseep_range() uses hrtimers and provides no advantage over msleep() for larger delays. Fix up the 100ms delays here passing the adjusted "min" value to msleep(). This helps reduce the load on the hrtimer subsystem.
