Subject: ab8500_fg: Replace msleep() with usleep_range() for greater accuracy
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=9a0bd070fd3582aed024a2f13a30b1de307db1e2;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

ab8500_fg: Replace msleep() with usleep_range() for greater accuracy

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.
