From ee1537fe3dd89860d0336563891f6cac707d0cb5 Mon Sep 17 00:00:00 2001 From: Weili Qian Date: Sat, 24 Sep 2022 19:04:31 +0800 Subject: crypto: hisilicon/qm - re-enable communicate interrupt before notifying PF After the device is reset, the VF needs to re-enable communication interrupt before the VF sends restart complete message to the PF. If the interrupt is re-enabled after the VF notifies the PF, the PF may fail to send messages to the VF after receiving VF's restart complete message.
