From af1ac18a19b80f922046fd383a3a3e780ee94915 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Wed, 23 Jan 2013 11:27:56 +0300 Subject: [PATCH] drm/nouveau/disp: sizeof() wrong pointer "data" is a void pointer and "args" is "data" after we have casted it to a struct. We care about the size of the struct here. Btw, sizeof(*data) is 1.
