[PATCH] x86/apic/msi: Unbreak DMAR and HPET MSI
STALE1358d
LANDED
From: Thomas Gleixner <hidden>
Date: 2020-09-27 08:46:49
Also in:
linux-iommu, linux-next, linux-pci, lkml, xen-devel
Landed in mainline as d27e623ace6a on 2020-09-27.
Switching the DMAR and HPET MSI code to use the generic MSI domain ops
missed to add the flag which tells the core code to update the domain
operations with the defaults. As a consequence the core code crashes
when an interrupt in one of those domains is allocated.
Add the missing flags.
Fixes: 9006c133a422 ("x86/msi: Use generic MSI domain ops")
