CVE-2025-39896: accel/ivpu: Prevent recovery work from being queued during device removal
In the Linux kernel, the following vulnerability has been resolved:
accel/ivpu: Prevent recovery work from being queued during device removal
Use disableworksync() instead of cancelworksync() in ivpudevfini() to ensure that no new recovery work items can be queued after device removal has started. Previously, recovery work could be scheduled even after canceling existing work, potentially leading to use-after-free bugs if recovery accessed freed resources.
Rename ivpupmcancelrecovery() to ivpupmdisablerecovery() to better reflect its new behavior.
