From: Greg Kroah-Hartman <gregkh@linuxfoundation.org> mainline inclusion from mainline-v5.7-rc4 commit ae74c19faa7d7996e857e13165bd40fc4a285e0d category: bugfix bugzilla: 34842, https://gitee.com/openeuler/kernel/issues/I6H9U5 CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?i... -------------------------------- In commit a7ba5c3d008d ("drivers/iommu: Export core IOMMU API symbols to permit modular drivers") a bunch of iommu symbols were exported, all with _GPL markings except iommu_group_get_for_dev(). That export should also be _GPL like the others.
