From a7db50405216610c8a0d62b8b400180b6f366733 Mon Sep 17 00:00:00 2001 From: Alex Chiang Date: Mon, 22 Jun 2009 08:08:07 -0600 Subject: PCI: remove pcibios_scan_all_fns() This was #define'd as 0 on all platforms, so let's get rid of it. This change makes pci_scan_slot() slightly easier to read. Cc: Yoshinori Sato Cc: Tony Luck Cc: David Howells Cc: "David S.
