Thanks Cascardo pointing out that patch a13c97118749 ("crypto: hisilicon/sec2 -
Add workqueue for SEC driver.") is also needed and in order to cherry-pick it,
we need to cherry-pick eaebf4c3b103 ("crypto: hisilicon - Unify hardware error
init/uninit into QM") too.
I am testing patched kernel and see if any more issue shall be noted.
