Hi all,

After merging the iommu tree, today's linux-next build (x86_64
allmodconfig) failed like this:

drivers/iommu/apple-dart.c: In function 'apple_dart_get_resv_regions':
drivers/iommu/apple-dart.c:758:2: error: implicit declaration of function 'iommu_dma_get_resv_regions'; did you mean 'iommu_get_resv_regions'? [-Werror=implicit-function-declaration]
758 | iommu_dma_get_resv_regions(dev, head);
| ^~~~~~~~~~~~~~~~~~~~~~~~~~
| iommu_get_resv_regions
cc1: all warnings being treated as errors

Caused by commit

b2b2781a9755 ("iommu/dart: Clean up IOVA cookie crumbs")

interactig with commit

05dc551614a4 ("iommu/dart: Exclude MSI doorbell from PCIe device IOVA range")

from the pci tree.

I have applied the following merge fix patch.
