linux-next: build failure after merge of the irqchip tree

[broonie]

Hi all,

After merging the irqchip tree, today's linux-next build (arm64
defconfig) failed like this:

/tmp/next/build/drivers/irqchip/irq-imx-mu-msi.c:14:10: fatal error: linux/dma-iommu.h: No such file or directory
   14 | #include <linux/dma-iommu.h>
      |          ^~~~~~~~~~~~~~~~~~~

Caused by commit

  841e6e9f2bc95baff ("irqchip: Add IMX MU MSI controller driver")

interacting with

  f2042ed21da7f8886 ("iommu/dma: Make header private")

I have reverted the driver for today.
