Hi all,

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

drivers/hwtracing/ptt/hisi_ptt.c:13:10: fatal error: linux/dma-iommu.h: No such file or directory
   13 | #include <linux/dma-iommu.h>
      |          ^~~~~~~~~~~~~~~~~~~

Caused by commit

  ff0de066b463 ("hwtracing: hisi_ptt: Add trace function support for HiSilicon PCIe Tune and Trace device")

interacting with commit

  f2042ed21da7 ("iommu/dma: Make header private")

from the iommu tree.

Since the public interfaces in dna-iommu.h were moved to iommu.h, I have
applied the following merge fix patch:
