Message-Id: <1406635107-27950-7-git-send-email-abbotti@mev.co.uk> Date: Tue, 29 Jul 2014 12:58:14 +0100 From: Ian Abbott <abbotti@....co.uk> To: driverdev-devel@...uxdriverproject.org Cc: Greg Kroah-Hartman <gregkh@...uxfoundation.org>, Ian Abbott <abbotti@....co.uk>, H Hartley Sweeten <hartleys@...ionengravers.com>, linux-kernel@...r.kernel.org Subject: [PATCH 06/19] staging: comedi: amplc_pci230: usleep_range is preferred over udelay Fix checkpatch issue: "CHECK: usleep_range is preferred over udelay; see Documentation/timers/timers-howto.txt". I picked 100 us as a reasonable upper bound, but it's not that critical.
