Subject: [PATCH] crypto: qat - re-enable interrupts for legacy PFVF messages
Git-commit: 04cf47872c7edde7a11c634aef04b1dbcf9c26fa
Patch-mainline: v5.17-rc1
References: jsc#PED-1073
If a PFVF message with MSGORIGIN_SYSTEM not set is received, re-enable
interrupts allowing the processing of new messages.
This is to simplify the refactoring of the recv function in a subsequent
patch.
