Subject[168/197] Input: wacom - switch mode upon system resume
2.6.32-stable review patch.  If anyone has any objections, please let us know.

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

From: Ping Cheng <pingc@wacom.com>

commit 014f61504af276ba9d9544d8a7401d8f8526eb73 upstream.

When Wacom devices wake up from a sleep, the switch mode command
(wacom_query_tablet_data) is needed before wacom_open is called.
wacom_query_tablet_data should not be executed inside wacom_open
since wacom_open is called more than once during probe.
