It appears that some kernel configurations do not include timer.h in any of the include files that are included by dahdi_dummy. The timer_structs are defined in timer.h and not time.h, so this change is correct even though I never could find a configuation myself that actually failed to compile. This has negligible impact since dahdi_dummy is not compiled by default.
