From f9f6971ebb75f5bc302d77e3380dd6363cc1a0f6 Mon Sep 17 00:00:00 2001 From: Thierry Reding Date: Wed, 18 Dec 2019 14:42:01 +0100 Subject: iommu: Implement generic_iommu_put_resv_regions() Implement a generic function for removing reserved regions. This can be used by drivers that don't do anything fancy with these regions other than allocating memory for them.
