From 3fe6929bbbca11b015d182d4864d92d0bf5c244d Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Wed, 5 Aug 2015 10:45:20 -0700 Subject: [PATCH] staging: comedi: me4000: usleep_range is preferred over udelay Fix checkpatch issue: "CHECK: usleep_range is preferred over udelay; see Documentation/timers/timers-howto.txt". `udelay()` is only used in the firmware upload process. Replace them with `usleep_range()` with a reasonable upper limit.
