[PATCH 0/2] gigaset USB drivers: suspend support

The following two patches add minimal suspend/resume support to the
USB based Gigaset ISDN drivers, bas_gigaset and usb_gigaset. Only
the USB aspects are handled so far; the ISDN subsystem is not
notified in any way, for lack of information about how to do that.

The base driver (bas_gigaset) will not close an open ISDN connection,
but refuse to suspend if a connection is active. The M105 driver
(usb_gigaset) ignores active connections, so as the device is powered
from USB, any connection will drop when the USB port is powered down.
These are policy decisions and as such open to discussion.

This code survives a "test mode" STD without any ill effects. I could
not test a "real" suspend/resume cycle yet because so far I do not
have any test machine with working suspend.

Comments welcome.

Thanks,
Tilman
