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.
