| Subject: usb: dwc2: host: use msleep() for long delay |
| |
| From: Nicholas Mc Guire <hofrat@osadl.org> |
| |
| commit d3fe81d2ccc41b355e494413115c0c7c18426fa1 upstream. |
| |
| 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. |

| Fixes: commit 2938fc63e0c2 ("usb: dwc2: Properly account for the force mode delays") |
