From 1d4ed26fafb4250a1a9f9aba55de05062330ea5b Mon Sep 17 00:00:00 2001 From: Andre Przywara Date: Mon, 6 Mar 2017 01:13:38 +0000 Subject: video: cfb_console: fix 32-bit display on 64-bit architectures "unsigned long" is a lousy data type when it comes to match peripheral hardware registers with a fixed size. Just do the obvious and match a 32-bit display format with an "u32" data type for casting. This fixes the logo display on 64-bit architectures, which produced a black line on the right side of the logo with non-black backgrounds.
