From 216a1d7da0660dd7d5f79c48e117de8d8d2da468 Mon Sep 17 00:00:00 2001 From: Ben Dooks Date: Wed, 21 Nov 2018 16:13:20 +0000 Subject: dmaengine: tegra: make byte counters unsigned int The buffer byte request length and counter are declared as signed integers but the values should never be below zero, so make these unsigned integers instead.
