Description
A vulnerability in the Linux kernel's drm/bridge synopsys dw-dp driver was fixed by adding support for unregistering the DisplayPort AUX channel. Previously, the AUX channel was registered during initialization but never unregistered, potentially causing resource leaks or use-after-free conditions. The fix introduces a dw_dp_unbind() function to properly clean up and unregister the AUX adapter.
