drm/i915: VLV2 - Fix hotplug detect bits
commit 232a6ee9af8adb185640f67fcaaa9014a9aa0573 upstream. Add new definitions for hotplug live status bits for VLV2 since they're in reverse order from the gen4x ones. Changelog: - Restored gen4 bit definitions - Added new definitions for VLV2 - Added platform check for IS_VALLEYVIEW() in dp_detect to use the correct bit defintions - Replaced a lost trailing brace for the added switch() Signed-off-by: Todd Previte <tprevite@gmail.com> Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=73951 [danvet: Switch to _VLV postfix instead of prefix and regroupg comments again so that the g4x warning is right next to those defines. Also add a _G4X suffix for those special ones. Also cc stable.] Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
