Subject: [PATCH] Input: mouse: navpoint - Change msleep to usleep_range for small msecs
Date: Mon, 28 Nov 2016 22:58:05 +0530 [thread overview]
Message-ID: <1480354085-1885-1-git-send-email-a.mathur@samsung.com> (raw)
msleep(1~20) may not do what the caller intends, and will often sleep longer.
(~20 ms actual sleep for any value given in the 1~20ms range)
This is not the desired behaviour for many cases like device resume time,
device suspend time, device enable time, retry logic, etc.
Thus, change msleep to usleep_range for precise wakeups.
