Subject[PATCH 5.10 277/563] iommu/amd: Remove iommu_init_ga()
Date
From: Suravee Suthikulpanit <suravee.suthikulpanit@amd.com>

[ Upstream commit eb03f2d2f6a4da25d286613717d10add9ce9f175 ]

Since the function has been simplified and only call iommu_init_ga_log(),
remove the function and replace with iommu_init_ga_log() instead.
