From d4526ab4e03bb16beee03547bfcbc1d8e09707f1 Mon Sep 17 00:00:00 2001 From: Ian Abbott Date: Tue, 6 May 2014 13:12:11 +0100 Subject: staging: comedi: pass subdevice to comedi_buf_is_mmapped() Change the parameters of `comedi_buf_is_mmapped()` to pass a pointer to the comedi subdevice instead of a pointer to the "async" structure belonging to the subdevice. The main aim at the moment is to replace all the `struct comedi_async *` parameters with `struct comedi_subdevice *` parameters in the comedi driver API.
