+Subject: [PATCH] Fixup hang on resume caused by the s3c2410 touch screen driver

+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.
