Message-id: <002e01cd738e$50fcfdc0$f2f6f940$%han@samsung.com> Date: Mon, 06 Aug 2012 13:45:34 +0900 From: Jingoo Han <jg1.han@...sung.com> To: 'Andrew Morton' <akpm@...ux-foundation.org>, 'LKML' <linux-kernel@...r.kernel.org> Cc: 'Richard Purdie' <rpurdie@...ys.net>, 'Claudio Nieder' <private@...udio.ch>, 'Jingoo Han' <jg1.han@...sung.com> Subject: [PATCH 3/3] backlight: kb3886: 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.
