From 2fb5cd385cb7ed56ce1ffd24264c3d5584972345 Mon Sep 17 00:00:00 2001 From: Ian Abbott Date: Wed, 16 Oct 2013 14:40:24 +0100 Subject: [PATCH] staging: comedi: ni_at_a2150: sample types are unsigned Sample values in comedi are generally represented by unsigned values. Change the type of the `dma_buffer` member of `struct a2150_private` from `s16 *` to `uint16_t *`, and change the type of the `dpnt` variable in `a2150_interrupt()` to `unsigned short` for consistency.
