Subject: [PATCH 1/2] iommufd: import IOMMUFD_INTERNAL namespace

From: Arnd Bergmann <arnd@...db.de>

Building the iommufd driver as a loadable module causes a failure now:

ERROR: modpost: module iommufd_driver uses symbol iommu_attach_handle_get from namespace IOMMUFD_INTERNAL, but does not import it.

Import the namespace as needed here.

Fixes: 916a207692ce ("iommufd: Move iommufd_sw_msi and related functions to driver.c")
