From 59e7999a440be5cb229cba87b3a0fb8392b094da Mon Sep 17 00:00:00 2001 From: John Crispin Date: Sun, 7 Dec 2014 16:53:09 +0000 Subject: ag71xx: replace delay with sleep calls I don't see that we're in an atomic context so there's no need to busy-wait. Therefore replace the delay with sleep calls. See also Documentation/timers/timers-howto.txt. It states: "In general, use of mdelay is discouraged and code should be refactored to allow for the use of msleep."
