commit e2127ae7a5e80eb53ad431c39145767391da40cd upstream.
Tegra124 was accidentally left out when the number of TLB lines was parameterized in commit 11cec15bf3fb ("iommu/tegra-smmu: Parameterize number of TLB lines"). Fortunately this doesn't cause any noticeable regressions upstream, presumably because there aren't any use-cases that exercise enough pressure on the SMMU. But it is a regression nonetheless, so let's fix it.
