    ide: do complete DMA setup in ->init_dma method (take 2) · b123f56e
    Bartlomiej Zolnierkiewicz authored
    * Make ide_hwif_setup_dma() return an error value.
    * Pass 'const struct ide_port_info *d' instead of 'unsigned long dmabase'
      to ->init_dma method and make it return an error value.
    * Rename ide_get_or_set_dma_base() to ide_pci_dma_base(),
      change ordering of its arguments and then export it.
    * Export ide_pci_set_master().
    * Do complete DMA setup inside ->init_dma method and update ->init_dma
      users accordingly.
    * Sanitize code for DMA setup in ide_init_port().
    * Fix for CONFIG_BLK_DEV_IDEDMA_PCI=n configs
      (from Jiri Slaby <jirislaby@gmail.com>):
      Fix following compiler warning by returning EINVAL:
      In file included from ANYTHING-INCLUDING-IDE.H:45:
      include/linux/ide.h: In function ‘ide_hwif_setup_dma’:
      include/linux/ide.h:1022: warning: no return statement in function returning non-void
