Subject: [PATCH 01/09] sh: pass along struct pci_channel
Date: Tue, 19 Feb 2008 12:34:28 +0000 [thread overview]
Message-ID: <20080219123428.4266.43660.sendpatchset@clockwork.opensource.se> (raw)
This patch makes sure a struct pci_channel pointer is passed along to
various pci functions such as pci_read_reg(), pci_write_reg(),
pci_fixup_pcic(), sh7751_pcic_init() and sh7780_pcic_init().
