From: Greg KH on 30 Mar 2010 19:50 2.6.33-stable review patch. If anyone has any objections, please let us know. ------------------ From: Tilman Schmidt <tilman(a)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.
