From caf8a518d73e71c4073ef1bd5c369e80d27ebf2c Mon Sep 17 00:00:00 2001 From: Joerg Roedel Date: Tue, 8 Jul 2014 12:53:32 +0200 Subject: [PATCH] iommu/amd: Don't call mmu_notifer_unregister in __unbind_pasid This function is called only in the mn_release() path, so there is no need to unregister the mmu_notifer here.
