The patch below was submitted to be applied to the 5.18-stable tree.
I fail to see how this patch meets the stable kernel rules as found at
Documentation/process/stable-kernel-rules.rst.
I could be totally wrong, and if so, please respond to

applied. Otherwise, it is now dropped from my patch queues, never to be
seen again.
thanks,

Subject: [PATCH] crypto: qat - re-enable registration of algorithms
Re-enable the registration of algorithms after fixes to (1) use
pre-allocated buffers in the datapath and (2) support the
CRYPTO_TFM_REQ_MAY_BACKLOG flag.
This reverts commit 8893d27ffcaf6ec6267038a177cb87bcde4dd3de.
