3.2.78-rc1 review patch.  If anyone has any objections, please let me know.

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

From: Oliver Neukum <oneukum@...e.com>

commit e912e685f372ab62a2405a1acd923597f524e94a upstream.

This phone needs to be handled by a specialised firmware tool
and is reported to crash irrevocably if cdc-acm takes it.
