From 192185d68dcc9b4517001fcec645111946f84d40 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Wed, 13 Apr 2016 10:31:14 +0200 Subject: [PATCH] iwlwifi: pcie: avoid msleep() with short timeout Since msleep is based on jiffies, it can sleep for a long time. Use usleep_range() instead to shorten the maximum time.
