The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - gpio: rcar: Use raw_spinlock to protect register access Use raw_spinlock in order to fix spurious messages     about invalid context when spinlock debugging is enabled. The lock is only used to serialize register     access.
