3.5.7.30 -stable review patch. If anyone has any objections, please let me know.
------------------
From: Johan Hovold <jhovold at gmail.com>
commit 440ebadeae9298d7de3d4d105342691841ec88d0 upstream.
Fix ring-indicator (RI) status-bit definition, which was defined as CTS,
effectively preventing RI-changes from being detected while reporting
false RI status.
This bug predates git.
