Affected: Alpaquita:stream: linux-lts

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

crypto: safexcel - Cleanup ring IRQ workqueues on load failure

A failure loading the safexcel driver results in the following warning on boot, because the IRQ affinity has not been correctly cleaned up. Ensure we clean up the affinity and workqueues on a failure to load the driver.
