From 164c8598450657d01fa75d6c997e95eb35672eef Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Sat, 20 Jul 2013 20:27:08 +0100 Subject: drm/i915: Add some debug breadcrumbs to connector detection Try to decypher detection failures is a little tricker at the moment as the only indicator of progress is when output_poll_execute() tells us the result after the connector->detect() has run. This patch adds a telltale to the start of each detect function so that we can track progress and associate activity more clearly with each connector.
