The code is mostly free of W=1 warning, so fix the following:
drivers/iommu/iommu.c:996: warning: expecting prototype for
iommu_group_for_each_dev(). Prototype was for __iommu_group_for_each_dev()
instead
drivers/iommu/iommu.c:3048: warning: Function parameter or member 'drvdata' not
described in 'iommu_sva_bind_device'
drivers/iommu/ioasid.c:354: warning: Function parameter or member 'ioasid' not
described in 'ioasid_get'
drivers/iommu/omap-iommu.c:1098: warning: expecting prototype for
omap_iommu_suspend_prepare(). Prototype was for omap_iommu_prepare() instead
