If anyone has any objections, please let me know. ------------------ From: Johan Hovold 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.
