| Subject: drm/radeon: set hpd polarity at init time so hotplug detect works |
| |
| From: Jerome Glisse <jglisse@redhat.com> |
| |
| 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. |
