Subject: [PATCH] <linux/pci.h> needs <linux/io.h> for ioremap_nocache()
Date: Wed, 22 Oct 2008 08:50:19 +0200 (CEST)	[thread overview]
Message-ID: <Pine.LNX.4.64.0810220848400.8356@anakin> (raw)

commit aa42d7c6138afdc54f74e971456a0fbfec16b77b ("PCI: introduce an
pci_ioremap(pdev, barnr) function") added a static inline function that calls
ioremap_nocache(), causing a compile error on m68k:

| In file included from drivers/ide/ide.c:58:
| include/linux/pci.h: In function 'pci_ioremap_bar':
| include/linux/pci.h:1132: error: implicit declaration of function 'ioremap_nocache'
| include/linux/pci.h:1133: warning: return makes pointer from integer without a cast
| In file included from include/linux/bio.h:30,
|                  from include/linux/blkdev.h:17,
|                  from include/linux/ide.h:13,
|                  from drivers/ide/ide.c:59:

Include <linux/io.h> to provide the prototype for ioremap_nocache().

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
