+Subject: crypto: hisilicon/qm - inject error before stopping queue
+
+From: Weili Qian <qianweili@huawei.com>
+
+commit b04f06fc0243600665b3b50253869533b7938468 upstream.
+
+The master ooo cannot be completely closed when the
+accelerator core reports memory error. Therefore, the driver
+needs to inject the qm error to close the master ooo. Currently,
+the qm error is injected after stopping queue, memory may be
+released immediately after stopping queue, causing the device to
+access the released memory. Therefore, error is injected to close master
+ooo before stopping queue to ensure that the device does not access
+the released memory.
+
+Fixes: 6c6dd5802c2d ("crypto: hisilicon/qm - add controller reset interface")
