AI-suggested

Apply the official patch that enforces holding bridge_lock during list operations in drm_bridge_add(). The affected Linux kernel versions listed should be updated to fixed versions once available. No other mitigation is indicated.

Description

A vulnerability in the Linux kernel's drm_bridge_add() function was fixed to prevent list corruption. The issue involved modifying bridge_lingering_list without holding the required bridge_lock, potentially corrupting internal kernel lists when re-adding a previously removed bridge.
