    ide: remove CONFIG_IDEDMA_{ICS,PCI}_AUTO config options · 120b9cfd

    All modern distributions have been setting these options to "y" for ages.
    (additionally "n" cases have been obsoleted for few years).  Therefore use
    DMA by default and remove CONFIG_IDEDMA_{ICS,PCI}_AUTO (also remove no longer
    needed CONFIG_IDEDMA_AUTO).  This fixes DMA support for rare configurations
    where CONFIG_IDEDMA_{ICS,PCI}_AUTO was set to "n" but "hdparm -d 1" was used
    to enable DMA support and which were forced to PIO mode by "ide: don't allow
    DMA to be enabled if CONFIG_IDEDMA_{ICS,PCI}_AUTO=n" patch.  There is no
    functionality loss because "ide=nodma" kernel option is still available.
