Subject: [PATCH 0/2] Gigaset driver patches for 2.6.31-rc1

Dave,

following are 2 patches for the Gigaset driver which I would
appreciate getting into 2.6.31. The first one is a bugfix which
should also go into stable.

Thanks,
Tilman

Subject: [PATCH 1/2] gigaset: accept connection establishment messages in any order

ISDN connection setup failed if the "connection active" and
"B channel up" messages from the device arrived in a different
order than expected. Modify the state machine to accept them in
any order.

Impact: bugfix
