From 1d98d0ec0ef3594901c2356773c191304703f17e Mon Sep 17 00:00:00 2001 From: Bartosz Golaszewski <bgolaszewski@baylibre.com> Date: Mon, 11 Apr 2016 11:57:21 -0700 Subject: [PATCH] eeprom: at24: replace msleep() with usleep_range() We cannot expect msleep(1) to actually sleep for a period shorter than 20 ms.
