Subject: USB: cypress_m8: fix ring-indicator detection and reporting
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.
