From d544d623c5ef3ca14407e8bc042fdf938a966b04 Mon Sep 17 00:00:00 2001 From: Ben Skeggs Date: Wed, 10 Mar 2010 15:52:43 +1000 Subject: drm/nv50: fix connector table parsing for some cards The connector table index in the DCB entry for each output type is an index into the connector table, and does *not* necessarily match up with what was previously called "index" in the connector table entries themselves. Not real sure what that index is exactly, renamed to "index2" as we still use it to prevent creating multiple TV connectors.
