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. Fixes: commit 4d33615df58b ("iio: light: add MAX30100 oximeter driver support") Link: http://lkml.org/lkml/2017/1/11/377 Signed-off-by: Nicholas Mc Guire <hofrat@osadl.org> Reviewed-by: Matt Ranostay <matt.ranostay@konsulko.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
