Subject: staging: comedi: das08.h: make self-reliant
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=3c7cab30f4c4364f72ccd7a034cf81fba7700525;p=linux-beck.git

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
<linux/types.h> to declare it.
