Borislav Petkov 776bb0270e ide-tape: use drive->pc_callback instead of pc->callback
The if-else block in the IRQ handler is only temporary so that bisect searches
don't break and it'll be removed after converting the remainder of the drivers.

Borislav Petkov 2207fa5af1 ide-floppy: use drive->pc_callback instead of pc->callback
It is important that drive->pc_callback is set prior to enabling IRQs on the
device since this is called from the IRQ handler. Otherwise it hurts as I learnt
the hard way from the several "Kernel panic - not synching: Fatal exception in
interrupt" during the weekend :).

The if-else block in the IRQ handler is only temporary so that bisect searches
don't break and it'll be removed after converting the remainder of the drivers.
