[036/116] Input: wacom - ensure the device is initialized properly upon resume

From: Greg KH
Date: Tue Mar 30 2010 - 20:12:43 EST


2.6.32-stable review patch. If anyone has any objections, please let us know.

------------------

From: Ping Cheng <pingc@xxxxxxxxx>

commit 232f5693e5c9483e222528ef81979e42ea2f2908 upstream.

Call wacom_query_tablet_data() from wacom_resume() so the device will be
switched to Wacom mode upon resume. Devices that require this are: regular
tablets and two finger touch devices.
