This patch adds an init callback to struct pci_channel and makes sure it is initialized properly. Code is added to call this init function from pcibios_init(). Return values are adjusted and a warning is is printed if init fails. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
