Ubuntu: (Multiple Advisories) (CVE-2025-38419): Linux kernel vulnerabilities

In the Linux kernel, the following vulnerability has been resolved:

remoteproc: core: Cleanup acquired resources when rproc_handle_resources() fails in rproc_attach()

When rproc->state = RPROC_DETACHED and rproc_attach() is used
to attach to the remote processor, if rproc_handle_resources()
returns a failure, the resources allocated by imx_rproc_prepare()
should be released, otherwise the following memory leak will occur.

Since almost the same thing is done in imx_rproc_prepare() and
rproc_resource_cleanup(), Function rproc_resource_cleanup() is able
to deal with empty lists so it is better to fix the "goto" statements
in rproc_attach(). replace the "unprepare_device" goto statement with
"clean_up_resources" and get rid of the "unprepare_device" label.
