From de1d5713a20562acdb3f94466232432c9dd1d95c Mon Sep 17 00:00:00 2001 From: Xiang Chen Date: Mon, 24 Sep 2018 23:06:32 +0800 Subject: [PATCH 05/31] scsi: hisi_sas: unmask interrupts ent72 and ent74 Origin: https://git.kernel.org/linus/6ecf5ba13cd5959eb75f617ff32c93bb67790e48 The interrupts of ent72 and ent74 are not processed by PCIe AER handling, so we need to unmask the interrupts and process them first in the driver.
