Subject[PATCH 04/18] power: ab8500_fg: Replace msleep() with usleep_range() for greater accuracy
Date
From: Jonas Aaberg <jonas.aberg@stericsson.com>

Doing so provides a greater degree of accuracy when dealing with
time-frames between 1us and 20ms. msleep() is only accurate for
wake-ups greater than 20ms.
