From 02112260acca09b11f96450c58420ec9312ae6fc Mon Sep 17 00:00:00 2001 From: Matt Ranostay Date: Mon, 9 Apr 2018 23:18:22 -0700 Subject: [PATCH] iio: chemical: atlas-ph-sensor: use msleep() for long uncritical delays usleep_range() uses hrtimers and provides no advantage over msleep() for larger delays.
