gpu: drm: omapdrm: Adding new typedef vm_fault_t 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 1c8f422059ae ("mm: change return type to vm_fault_t") Previously vm_insert_mixed() returns err which driver mapped into VM_FAULT_* type. Also return value of vm_insert_mixed() not handled correctly and 0 was returned inside fault_2d() as default. The new function vmf_insert_mixed() will replace this inefficiency by returning correct VM_FAULT_* type. vmf_error() is the newly introduce inline function in 4.17-rc6.
