From 3c7cab30f4c4364f72ccd7a034cf81fba7700525 Mon Sep 17 00:00:00 2001 From: Ian Abbott Date: Fri, 5 Jun 2015 18:30:09 +0100 Subject: [PATCH] staging: comedi: das08.h: make self-reliant The Comedi "das08.h" header file is included by drivers for the ComputerBoards/MeasurementComputing and Keithley Metrabyte boards in the DAS08 series. It does not compile cleanly when it is the first header included by the ".c" file. It uses `struct comedi_device *` in the parameter list of a function prototype, so just declare `struct comedi_device` as an incomplete type. It also uses `bool`, so include to declare it.
