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.
