Subject: [PATCH] staging: qlge: change msleep to usleep_range
Date: Sun, 13 Jun 2021 22:11:30 -0400	[thread overview]
Message-ID: <YMa60p5dl0LMV/9D@tobias-VirtualBox> (raw)

This patch changes msleep() to usleep_range() based on
Documentation/timers/timers-howto.txt. It suggests using usleep_range()
for small msec(1ms - 20ms) because msleep() will often sleep longer than
the desired value. Issue found by checkpatch.
