CVE-2026-93195

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/bridge: synopsys: dw-dp: Support unregistering the AUX channel
The DisplayPort AUX channel gets initialized and registered during dw_dp_bind(), but it is never unregistered, which may lead to resource leaks and/or use-after-free.
Add the missing dw_dp_unbind() function to allow the users of the library to handle the required cleanup, i.e. unregister the AUX adapter.
