Hi Miles,
Thank you for the patch! Perhaps something to improve:
[auto build test WARNING on joro-iommu/next]
[also build test WARNING on v5.18-rc3 next-20220422]
[If your patch is applied to the wrong git tree, kindly drop us a note.
And when submitting patch, we suggest to use '--base' as docum
When larbdev is NULL (in the case I hit, the node is incorrectly set
iommus = <&iommu NUM>), it will cause device_link_add() fail and
the kernel crashes when we try to print dev_name(larbdev).
Fix it by adding a NULL pointer check before
device_link_add/device_link_remove.
It should work for norm
