From 92b9618761465d190b68519bcc6a6fbd8847cf2c Mon Sep 17 00:00:00 2001 From: Ben Skeggs Date: Mon, 10 May 2010 16:59:42 +1000 Subject: [PATCH] drm/nouveau: display error message for any failed init table opcode Some handlers don't report specific errors, but we still *really* want to know if we failed to parse a complete init table.
