Title
drm/xe/nvm: Fix double-free on aux add failure
Summary
In the Linux kernel, the following vulnerability has been resolved: drm/xe/nvm: Fix double-free on aux add failure After a successful auxiliary_device_init(), aux_dev->dev.release (xe_nvm_release_dev()) is responsible for the kfree(nvm). When there is failure with auxiliary_device_add(), driver will call auxiliary_device_uninit(), which call put_device(). So that the .release callback will be triggered to free the memory associated with the auxiliary_device. Move the kfree(nvm) into the auxiliary_device_init() failure path and remove the err goto path to fix below error.
