Subject: [PATCH 3.12 102/116] cdc-acm:exclude Samsung phone 04e8:685d

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

3.12-stable review patch.  If anyone has any objections, please let me know.

===============

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.
