Signed-off-by: Maciej W. Rozycki <macro@xxxxxxxxxxxxxx> --- Not much to say beyond the subject. Noticed while fiddling with a plain ISA multi-I/O card (remember those?) having a single IDE channel only, as usually with them, to avoid errors like: ide1: unexpected interrupt, status=0xff, count=11 popping up in the kernel log -- presumably coming from noise on the floating IRQ15 line or maybe spurious interrupts triggered by another device (the slave 8259A delivers them like IRQ15 and they can be told apart by internal PIC status, but we don't check it if the line is enabled, for performance reasons). Please apply.
