[PATCH 2/3] gigaset: correct clearing of at_state strings on RING

From: Tilman Schmidt
Date: Sun Mar 14 2010 - 19:01:11 EST


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
Signed-off-by: Tilman Schmidt <tilman@xxxxxxx>
CC: stable@xxxxxxxxxx

Note to -stable: applies correctly to 2.6.33.
