parisc: ccio-dma: Create private runway procfs root entry
Create an own procfs "runway" root entry for the CCIO driver. No need to share it with the sba_iommu driver, as only one of those busses can be active in one machine anyway. Signed-off-by: Helge Deller <deller@gmx.de> Reported-by: kernel test robot <lkp@intel.com> Fixes: 547259580dfa ("parisc: Move proc_mckinley_root and proc_runway_root to sba_iommu") Cc: <stable@vger.kernel.org> # v6.5
