CVE-2025-39699

In the Linux kernel, the following vulnerability has been resolved:

iommu/riscv: prevent NULL deref in iova_to_phys

The riscv_iommu_pte_fetch() function returns either NULL for
unmapped/never-mapped iova, or a valid leaf pte pointer that
requires no further validation.

riscv_iommu_iova_to_phys() failed to handle NULL returns.
Prevent null pointer dereference in
riscv_iommu_iova_to_phys(), and remove the pte validation.
