Implementing ops->capable to always return false is pointless since it's the default behaviour anyway. Clean up the unnecessary implementations.
Signed-off-by: Robin Murphy <robin.mur...@arm.com> --- Spinning this out of my bus ops stuff (currently 30 patches and counting...) since it would be better off alongside Baolu's cleanup series to avoid conflicts, and I want to depend on those patches for dev_iommu_ops() anyway. drivers/iommu/msm_iommu.c | 6 ------ drivers/iommu/tegra-gart.c | 6 ------ drivers/iommu/tegra-smmu.c | 6 ------ 3 files changed, 18 deletions(-) diff --git a/drivers/iommu/msm_iommu.c b/drivers/iommu/msm_iommu.c index 06bde6b66732..22061ddbd5df 100644 --- a/drivers/iommu/msm_iommu.c +++ b/drivers/iommu/msm_iommu.c @@ -558,11 +558,6 @@ static phys_addr_t msm_iommu_iova_to_phys(struct iommu_domain *domain, return ret; } -static bool msm_iommu_capable(enum iommu_cap cap) -{ - return false; -} - static void print_ctx_regs(void __iomem *base, int ctx) { unsigned int fsr = GET_FSR(base, ctx); @@ -672,7 +667,6 @@ irqreturn_t msm_iommu_fault_handler(int irq, void *dev_id) } static struct iommu_ops msm_iommu_ops = { - .capable = msm_iommu_capable, .domain_alloc = msm_iommu_domain_alloc, .domain_free = msm_iommu_domain_free, .attach_dev = msm_iommu_attach_dev, diff --git a/drivers/iommu/tegra-gart.c b/drivers/iommu/tegra-gart.c index 6a358f92c7e5..bbd287d19324 100644 --- a/drivers/iommu/tegra-gart.c +++ b/drivers/iommu/tegra-gart.c @@ -238,11 +238,6 @@ static phys_addr_t gart_iommu_iova_to_phys(struct iommu_domain *domain, return pte & GART_PAGE_MASK; } -static bool gart_iommu_capable(enum iommu_cap cap) -{ - return false; -} - static struct iommu_device *gart_iommu_probe_device(struct device *dev) { if (!dev_iommu_fwspec_get(dev)) @@ -276,7 +271,6 @@ static void gart_iommu_sync(struct iommu_domain *domain, } static const struct iommu_ops gart_iommu_ops = { - .capable = gart_iommu_capable, .domain_alloc = gart_iommu_domain_alloc, .domain_free = gart_iommu_domain_free, .attach_dev = gart_iommu_attach_dev, diff --git a/drivers/iommu/tegra-smmu.c b/drivers/iommu/tegra-smmu.c index e900e3c46903..43df44f918a1 100644 --- a/drivers/iommu/tegra-smmu.c +++ b/drivers/iommu/tegra-smmu.c @@ -272,11 +272,6 @@ static void tegra_smmu_free_asid(struct tegra_smmu *smmu, unsigned int id) clear_bit(id, smmu->asids); } -static bool tegra_smmu_capable(enum iommu_cap cap) -{ - return false; -} - static struct iommu_domain *tegra_smmu_domain_alloc(unsigned type) { struct tegra_smmu_as *as; @@ -967,7 +962,6 @@ static int tegra_smmu_of_xlate(struct device *dev, } static const struct iommu_ops tegra_smmu_ops = { - .capable = tegra_smmu_capable, .domain_alloc = tegra_smmu_domain_alloc, .domain_free = tegra_smmu_domain_free, .attach_dev = tegra_smmu_attach_dev, -- 2.28.0.dirty _______________________________________________ iommu mailing list iommu@lists.linux-foundation.org https://lists.linuxfoundation.org/mailman/listinfo/iommu
