From 6a088a2cbcaf40747cf2881df47f4f5d65acd7ab Mon Sep 17 00:00:00 2001 From: Weili Qian Date: Sat, 13 Aug 2022 18:35:45 +0800 Subject: [PATCH] crypto: hisilicon/qm - remove unneeded hardware cache write back Data in the hardware cache needs to be written back to the memory before the queue memory is released. Currently, the queue memory is applied for when the driver is loaded and released when the driver is removed. Therefore, the hardware cache does not need to be written back when process puts queue.
