X-Git-Tag: v6.13-rc1~105^2~1^7~18
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=fae93d8da6b94ca1a6a497e8a00ad87324188cf7;p=thirdparty%2Fkernel%2Flinux.git

remoteproc: Use iommu_paging_domain_alloc()

An iommu domain is allocated in rproc_enable_iommu() and is attached to
rproc->dev.parent in the same function.

Use iommu_paging_domain_alloc() to make it explicit.
