From 94e1b6af99b3548014686a0943bb286e3c81a889 Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Sat, 22 Mar 2014 14:45:50 +0100 Subject: lib: rename intel_pci.c to intel_chipset.c This is to consolidate all the chipset related functions to intel_chipset.[hc]. Unfortunately we need to rename a wrapper lib file in quick_dump, too. And quick_dump makes automake a bit unhappy apparently.
