    [PATCH] ide: fix HPT3xx hotswap support · 33b18a60
    Sergei Shtylyov authored
    Fix the broken hotswap code: on HPT37x it caused RESET- to glitch when
    tristating the bus (the MISC control 3/6 and soft control 2 need to be written
    to in the certain order), and for HPT36x the obsolete HDIO_TRISTATE_HWIF
    ioctl() handler was called instead which treated the state argument wrong.
    Also, get rid of the soft control reg.  1 wtite to enable IDE interrupt --
    this is done in init_hpt37x() already...
    Have been tested on HPT370 and 371N.
