From 0632fef669912a63c99c8ce4c2ca10c6ea04f0df Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Tue, 8 Oct 2013 17:44:49 +0200 Subject: drm/i915: rename intel_fb.c to intel_fbdev.c This file is all about the legacy fbdev support. If we want to extract framebuffer functions, we better put those into a separate file. Also rename functions accordingly, only two have used the intel_fb_ prefix anyway.
