From 8b18d5f5454e044228f5093ae932333753f00e67 Mon Sep 17 00:00:00 2001 From: Bharat Bhushan Date: Mon, 11 Dec 2023 15:59:11 +0530 Subject: [PATCH] crypto: octeontx2 - Fix cptvf driver cleanup [ Upstream commit c480a421a4faf693c38e60b0fe6e554c9a3fee02 ] This patch fixes following cleanup issues: - Missing instruction queue free on cleanup. This will lead to memory leak. - lfs->lfs_num is set to zero before cleanup, which will lead to improper cleanup.
