From 7b7d70785f1b3c1421d56ee8140578fea3b90f9c Mon Sep 17 00:00:00 2001 From: Holger Freyther Date: Thu, 15 May 2008 21:47:56 +0100 Subject: [PATCH] Fixup hang on resume caused by the s3c2410 touch screen driver From dc6d335b467646d802a21ea6b925ee97e83e07be Mon Sep 17 00:00:00 2001 From: Holger Freyther Date: Thu, 15 May 2008 01:16:23 +0200 Subject: [PATCH] Do not use msleep in the resume path of s3c2410_ts as it might lockup For some reason msleep might set the only task running into a suspended state and no timer will ever wake it up. Use mdelay to avoid this. I was not able to understand the reasoning of sleeping after enabling the clock. So we might just remove the msleep/mdelay at all and be fine.
