[PATCH] iommufd: fixing build warnings after merging the iommufd tree

From: Bragatheswaran Manickavel
Date: Mon Oct 23 2023 - 04:56:05 EST


After merging the iommufd tree, today's linux-next build (htmldocs)
produced these warnings:

include/uapi/linux/iommufd.h:433: warning: expecting prototype for enum iommufd_hw_info_capabilities. Prototype was for enum iommufd_hw_capabilities instead
include/uapi/linux/iommufd.h:497: warning: Function parameter or member '__reserved' not described in 'iommu_hwpt_set_dirty_tracking'
include/uapi/linux/iommufd.h:512: warning: expecting prototype for enum iommufd_get_dirty_bitmap_flags. Prototype was for enum iommufd_hwpt_get_dirty_bitmap_flags instead
include/uapi/linux/iommufd.h:542: warning: Function parameter or member '__reserved' not described in 'iommu_hwpt_get_dirty_bitmap'
