From 346add7834557b5b9628b9bf2387106d42e631d4 Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Tue, 14 Jul 2015 18:07:30 +0200 Subject: drm/i915: Use expcitly fixed type in compat32 structs I was confused shortly whether the compat was needed for the int, until I noticed the pointer in the original. Also remove typedef. v2: Review from Chris. - Add comments. - Also change the int param in the original structure.
