From 18e2452a3c4e830bff9628ec0e25a814df491e30 Mon Sep 17 00:00:00 2001 From: Nicholas Mc Guire Date: Mon, 16 Jan 2017 16:35:53 +0100 Subject: iio: health: max30100: use msleep() for long uncritical delays ulseep_range() uses hrtimers and provides no advantage over msleep() for larger delays. Fix up the 35ms delays here to use msleep() and reduce the load on the hrtimer subsystem.
