scsi: cxlflash: Change return type for fault handler
Use new return type vm_fault_t for fault handler. For now, this is just documenting that the function returns a VM_FAULT value rather than an errno. Once all instances are converted, vm_fault_t will become a distinct type. Ref-> commit 1c8f4220 ("mm: change return type to vm_fault_t") Previously, VM_FAULT_NOPAGE was returned without verifying return value of vm_insert_pfn. The new inline vmf_insert_pfn() will address this issue by returning correct VM_FAULT_* type from fault handler. Signed-off-by: NSouptick Joarder <jrdr.linux@gmail.com> Acked-by: NMatthew R.
