Dan Carpenter	7798757013	drm/bridge: display-connector: fix an uninitialized pointer in probe() ... [ Upstream commit 189723fbe9aca18d6f7d638c59a40288030932b5 ] The "label" pointer is used for debug output. The code assumes that it is either NULL or valid, but it is never set to NULL. It is either valid or uninitialized.

Laurent Pinchart	0c275c3017	drm/bridge: Add bridge driver for display connectors ... Display connectors are modelled in DT as a device node, but have so far been handled manually in several bridge drivers. This resulted in duplicate code in several bridge drivers, with slightly different (and thus confusing) logics. In order to fix this, implement a bridge driver for display connectors. The driver centralises logic for the DVI, HDMI, VGAn composite and S-video connectors and exposes corresponding bridge operations. This driver in itself doesn't solve the issue completely, changes in bridge and display controller drivers are needed to make use of the new connector driver.
