Subject: [PATCH 1/2] iommufd: import IOMMUFD_INTERNAL namespace
Date: Mon, 24 Mar 2025 22:03:22 +0100	[thread overview]
Message-ID: <20250324210329.2809869-1-arnd@kernel.org> (raw)

From: Arnd Bergmann <arnd@arndb.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")
Signed-off-by: Arnd Bergmann <arnd@arndb.de>
