[PATCH] hw/isa/vt82c686: Keep track of PIRQ/PINT pins separately
Posted by BALATON Zoltan 1 month, 2 weeks ago
Move calculation of mask after the switch which sets the function
number for PIRQ/PINT pins to make sure the state of these pins are
kept track of separately and IRQ is raised if any of them is active.

Fixes: 7e01bd80c1 hw/isa/vt82c686: Bring back via_isa_set_irq()
Signed-off-by: BALATON Zoltan <balaton@eik.bme.hu>

Preferably for 9.0 if there will be another RC.
