From: Nicolin Chen Date: Thu, 23 Oct 2025 02:21:06 +0000 (-0700) Subject: iommu/exynos-iommu: Set release_domain to exynos_identity_domain X-Git-Tag: v6.19-rc1~133^2^8~59 X-Git-Url: https://gentwo.org/gitweb/?a=commitdiff_plain;h=680a6a60fc0846cb0364201f7625700da1e8ffa1;p=linux%2F.git iommu/exynos-iommu: Set release_domain to exynos_identity_domain Following a coming core change to pass in the old domain pointer into the attach_dev op and its callbacks, exynos_iommu_identity_attach() will need this new argument too, which the release_device op doesn't provide. Instead, the core provides a release_domain to attach to the device prior to invoking the release_device callback. Thus, simply use that.
