    ide: do complete DMA setup in ->init_dma method (take 2) · b123f56e

    * 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().
    
    v2:
    * Fix for CONFIG_BLK_DEV_IDEDMA_PCI=n configs
      (from Jiri Slaby <jirislaby@gmail.com>):
    
      Fix following compiler warning by returning EINVAL:
