From 52793ef05113658e6391230625f8762cc3905c8f Mon Sep 17 00:00:00 2001 From: Johan Hovold Date: Thu, 2 Jan 2014 22:49:24 +0100 Subject: [PATCH] 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.
