Subject: [PATCH 2/3] imx-drm: ipu-dc: Use usleep_range instead of msleep
Date: Tue, 25 Feb 2014 11:43:42 +0000 [thread overview]
Message-ID: <1393328624-28013-3-git-send-email-p.zabel@pengutronix.de> (raw)
Since msleep(2) can sleep up to 20ms anyway, make this explicit by using
usleep_range(2000, 20000).
