From 3c829d6d19ae2d7084f578e7fa99b1366f5a4602 Mon Sep 17 00:00:00 2001 From: Shukun Tan Date: Sat, 15 Aug 2020 17:56:09 +0800 Subject: [PATCH] crypto: hisilicon/qm - clear used reference count when start qp The used reference count is used for counting the number of 'sqe' which is under processing. This reference count should be cleared as starting 'qp', otherwise the 'used' will be messy when allocating this 'qp' again. Fixes: 5308f6600a39("crypto: hisilicon - QM memory management...")
