Subject: [083/117] cdc_ether: fix autosuspend for mbm devices

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

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


From: Torgny Johansson <torgny.johansson@...csson.com>

[ Upstream commit 55964d72d63b15df49a5df11ef91dc8601270815 ]

Autosuspend works until you bring the wwan interface up, then the
device does not enter autosuspend anymore.

The following patch fixes the problem by setting the .manage_power
field in the mbm_info struct to the same as in the cdc_info struct
(cdc_manager_power).
