From 3a62cdb7f64f80579ce18178ecc145f01c1ad746 Mon Sep 17 00:00:00 2001 From: Ian Abbott Date: Fri, 22 May 2015 18:45:25 +0100 Subject: [PATCH] staging: comedi: comedi_isadma.h: make self-reliant The Comedi "comedi_isadma.h" header is included by the source for the "comedi_isadma" helper module and other modules that use it. It does not compile cleanly when it is the first header file included. It uses the `dma_addr_t` type, so include to declare it. (Also, that indirectly takes care of the use of `NULL`.) It uses `struct comedi_device *` in various function prototypes, so add an incomplete declaration of `struct comedi_device`.
