[PATCH] ide: pdc202xx_old: remove the obsolete busproc
Remove the busproc from pdc202xx_old.c because: - it handles the obsolete HDIO_TRISTATE_HWIF ioctl instead of the modern HDIO_SET_BUSSTATE, so treats its argument wrong; - I don't think that tristating both channels is good idea (probably can't be done otherwise since there seems to be only single bit controlling this).
