Upstream commitb7cb9a0343("dmaengine: idxd: Fix refcount underflow on module unload") fixes a refcount underflow by replacing the call to idxd_cleanup() in the remove function with direct cleanup calls. That works fine upstream. However, upstream removed support for IOMMU_DEV_FEAT_IOPF, which is still supported in v6.12.y. The backport of commitb7cb9a0343into v6.12.y misses the call to disable it. This results in a warning backtrace when unloading and reloading the module. WARNING: CPU: 0 PID: 665849 at drivers/pci/ats.c:337 pci_reset_pri+0x4c/0x60 ... RIP: 0010:pci_reset_pri+0xa7/0x130 Add the missing cleanup call to fix the problem.
