From 7d3f04af69bed2db87d6a72d100e182f773e54b7 Mon Sep 17 00:00:00 2001 From: Jacob Keller Date: Wed, 5 Oct 2016 09:30:45 -0700 Subject: [PATCH] i40evf: avoid an extra msleep while Remove the second call to msleep outside the loop, and move the msleep within the loop as the first step. This guarantees that a single loop will wait the minimum time first, and then after the reset finishes we no longer need an extra msleep.
