Subject[048/116] gigaset: correct clearing of at_state strings on RING
2.6.32-stable review patch.  If anyone has any objections, please let us know.

------------------

From: Tilman Schmidt <tilman@imap.cc>

commit 3a0a3a6b92edf181f849ebd8417122392ba73a96 upstream.

In RING handling, clear the table of received parameter strings in
a loop like everywhere else, instead of by enumeration which had
already gotten out of sync.

Impact: minor bugfix
