Subject: [net-next 13/15] e1000e: cleanup USLEEP_RANGE checkpatch checks
From: Bruce Allan <bruce.w.allan@...el.com>
Resolve strict checkpatch USLEEP_RANGE checks by converting delays and
sleeps as described in ./Documentation/timers/timers-howto.txt. Three
other violations of the text have also been fixed.
CHECK:USLEEP_RANGE: usleep_range is preferred over udelay; see
Documentation/timers/timers-howto.txt
