[PATCH] huawei: ignore ^DSDORMANT unsolicited messages

[Enrico Mioso]

Interesting!!! :) Does this concept exist on 3G/UMTS/HSPA(+) ? I'm sure some 
modems are doing this in some way, but don't know if it's a different thing, 
might be handled in some way by software.
How can I detect if a zte or huawei modem (I ask about these two because I have 
them) supports dormancy? Note that I'm taling about 3G/UMTS/HSPA(+) modems, not 
Ev-Do ones.

==AFAIK dormancy applies to modems that supports data bearers.  At least
