From 7b7afb469cfe9eb384028f86ce4ec2fb8946f772 Mon Sep 17 00:00:00 2001 From: Ian Abbott Date: Tue, 5 May 2015 18:47:26 +0100 Subject: [PATCH] staging: comedi: gsc_hpdi: 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 called once from a place where sleeping is allowed. Replace it with a call to `usleep_range()` with a reasonable upper limit.
