ide: remove hwif->autodma and drive->autodma
* hpt34x.c: disable DMA masks for HPT345 (hwif->autodma is zero so DMA won't be enabled anyway). * trm290.c: disable IDE_HFLAG_TRUST_BIOS_FOR_DMA flag (hwif->autodma is zero so DMA won't be enabled anyway). * Check noautodma global variable instead of drive->autodma in ide_tune_dma(). This fixes handling of "ide=nodma" kernel parameter for icside, ide-cris, au1xxx-ide, pmac, it821x, jmicron, sgiioc4 and siimage host drivers. * Remove hwif->autodma (it was not checked by IDE core code anyway) and drive->autodma (was set by all host drivers - except HPT345/TRM290 special cases - unless "ide=nodma" was used). While at it: - remove needless printk() from icside.c - remove stale FIXME/comment from ide-probe.c - don't force DMA off if PCI bus-mastering had to be enabled in setup-pci.c (this setting was always later over-ridden by host drivers anyway) Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
