Subject: staging: comedi: serial2002: usleep_range is preferred over udelay
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=3335dfd1ab5f02915fb2aeeace41526f92d8b560;p=deliverable%2Flinux.git

staging: comedi: serial2002: usleep_range is preferred over udelay

Fix checkpatch issue: "CHECK: usleep_range is preferred over udelay;
see Documentation/timers/timers-howto.txt". Replace the udelay() with
usleep_range() with a reasonable upper limit.
