From 65a62aaec2e888b6271a4f302f10ad72e966cc10 Mon Sep 17 00:00:00 2001 From: Ian Abbott Date: Wed, 16 Oct 2013 14:40:18 +0100 Subject: staging: comedi: das1800: sample types are unsigned Sample values in comedi are generally represented by unsigned values. Change the type of the `ao_update_bits` member of `struct das1800_private` and the types of various local variables used to hold sample values from `short` to `unsigned short` for consistency.
