From e6b7481b83449b108597c129bc7fcfae63933753 Mon Sep 17 00:00:00 2001 From: Jingoo Han Date: Fri, 28 Sep 2012 10:20:16 +1000 Subject: [PATCH] drivers/video/backlight/kb3886_bl.c: use usleep_range() instead of msleep() for small sleeps Since msleep() might not sleep for the desired amount when less than 20ms, use usleep_range().
