CVE-2025-39906

In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: remove oem i2c adapter on finish Fixes a bug where unbinding of the GPU would leave the oem i2c adapter registered resulting in a null pointer dereference when applications try to access the invalid device. (cherry picked from commit 89923fb7ead4fdd37b78dd49962d9bb5892403e6)
