please fix siimage.c and core code instead
(please see libata-core.c and ata_host_stop() etc.)

- release the same number of DMA I/O ports that was requested by a driver

please fix trm290.c to use ->mmio == 2 instead

   It's a _really_ old chipset (pre SFF-8038i) and has _no_ memory mapped
regs AFAIK...

->mmio == 2 means _only_ that host driver is responsible
for reserving/releasing resources - it doesn't mean that host driver
is using MMIO (a bit confusing but this is what the current code does)

So, your point is that ide_setup_dma() should _never_ do anything for the (mmio == 2) case? Maybe it shouldn't even be called? I guess we surely need some driver cleanup hook to call ftom ide_release_dma()...

Thanks,
