CVE-2025-38419

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

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

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

Since almost the same thing is done in imxrprocprepare() and rprocresourcecleanup(), Function rprocresourcecleanup() is able to deal with empty lists so it is better to fix the "goto" statements in rprocattach(). replace the "unpreparedevice" goto statement with "cleanupresources" and get rid of the "unprepare_device" label.
