From ff356c22478a5487e2edaaad31f60bc3868c43f5 Mon Sep 17 00:00:00 2001 From: Jerome Glisse Date: Fri, 28 Oct 2011 17:52:34 -0400 Subject: [PATCH] drm/radeon: set hpd polarity at init time so hotplug detect works commit 8ab250d4484b72ccc78e34276c5ffa84c1d41303 upstream. Polarity needs to be set accordingly to connector status (connected or disconnected). Set it up at module init so first hotplug works reliably no matter what is the initial set of connector.
