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

From: Jonas Jonsson <jo...@ludd.ltu.se>
commit a0e80fbd56b4573de997c9a088a33abbc1121400 upstream.
The flash loader has been seen on a Telit UE910 modem. The flash loader
is a bit special, it presents both an ACM and CDC Data interface but
only the latter is useful. Unless a magic string is sent to the device
it will disappear and the regular modem device appears instead.
