Summary
In the Linux kernel, the following vulnerability has been resolved:
drm: zynqmp_dpsub: Always register bridge
We must always register the DRM bridge, since zynqmp_dp_hpd_work_func
calls drm_bridge_hpd_notify, which in turn expects hpd_mutex to be
initialized. We do this before zynqmp_dpsub_drm_init since that calls
drm_bridge_attach. This fixes the following lockdep warning:
