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.
