Upstream source description

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: Fix memory leak in amdgpu_acpi_enumerate_xcc() In amdgpu_acpi_enumerate_xcc(), if amdgpu_acpi_dev_init() returns -ENOMEM, the function returns directly without releasing the allocated xcc_info, resulting in a memory leak. Fix this by ensuring that xcc_info is properly freed in the error paths. Compile tested only. Issue found using a prototype static analysis tool and code review.
