Subject: iommu/amd: Remove iommu_init_ga()
X-Git-Url: https://git.kernel.dk/?a=commitdiff_plain;h=c2bd7c31de1a5f3bb5f9a30327c58501d08e2ad0;p=linux-block.git

iommu/amd: Remove iommu_init_ga()

[ 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.
