I noticed a kernel crash when trying to boot a v5.9-rc2 based kernel.

The crash reads as:

Full kernel message is attached in kernel.log.

I tracked the problem down to the dev_iommu_priv_set call in 
init_no_remapping_devices. It seems that for one device the dev->iommu member 
is NULL.

An dev_err outputs the device as "pci 0000:00:02.0: DMAR" which is the intel HD 
620 graphic adapter in a Lenovo T470s device.

The following patch (also attached as intel-iommu.patch) avoids this crash by 
checking the pointer.

DUMMY_DEVICE_DOMAIN_INFO);
                }
        }
 }

I assume the problem might be related to the following commit introduced in 
v5.9-rc1:

commit 01b9d4e21148c89fdbab3d6b3705f9791314b631
Author: Joerg Roedel <jroe...@suse.de>
Date:   Thu Jun 25 15:08:25 2020 +0200

    iommu/vt-d: Use dev_iommu_priv_get/set()
    
    Remove the use of dev->archdata.iommu and use the private per-device
    pointer provided by IOMMU core code instead.

With regards,

        Torsten Hilbrich
