From 18b3af4492a0aa6046b86d712f6ba4cbb66100fb Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Wed, 20 Feb 2019 14:05:05 +0100 Subject: [PATCH] iommu: Fix IOMMU debugfs fallout A change made in the final version of IOMMU debugfs support replaced the public function iommu_debugfs_new_driver_dir() by the public dentry iommu_debugfs_dir in , but forgot to update both the implementation in iommu-debugfs.c, and the patch description. Fix this by exporting iommu_debugfs_dir, and removing the reference to and implementation of iommu_debugfs_new_driver_dir().
