From 3388c37e04ec0e35ebc1b4c732fdefc9ea938f3b Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Fri, 6 Oct 2006 17:06:39 +0200 Subject: [ALSA] intel8x0 - Use pci_iomap Use pci_iomap and ioread*/iowrite*() functions for accessing hardwares. pci_iomap is suitable for hardwares like ICH and compatible that have both PIO and MMIO.
