Subject: ads7846: make the suspend function sleep instead of busy poll
X-Git-Tag: v2.6.16-omap1~59
X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=071a568a4d89c0bff7dd5e6a4906066be317db2c;p=linux-2.6-omap-h63xx.git

ads7846: make the suspend function sleep instead of busy poll

ads7846_suspend was busily polling for a couple of variables,
which never get a chance to change state unless kernel pre-emption
is enabled.  Use msleep instead.
