This is a note to let you know that I've just added the patch titled crypto: qat - set COMPRESSION capability for DH895XCC to the 5.15-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: crypto-qat-set-compression-capability-for-dh895xcc.patch and it can be found in the queue-5.15 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit dcce8d68e5c0c38d82cc0481c704f19e55144f83 Author: Giovanni Cabiddu <giovanni.cabiddu@xxxxxxxxx> Date: Thu Apr 7 17:54:41 2022 +0100 crypto: qat - set COMPRESSION capability for DH895XCC [ Upstream commit 0eaa51543273fd0f4ba9bea83638f7033436e5eb ] The capability detection logic clears bits for the features that are disabled in a certain SKU. For example, if the bit associate to compression is not present in the LEGFUSE register, the correspondent bit is cleared in the capability mask. This change adds the compression capability to the mask as this was missing in the commit that enhanced the capability detection logic.
