[PATCH 03/13] hw/isa/piix4: Resolve redundant i8259[] attribute
Posted by Philippe Mathieu-Daudé 3 years, 11 months ago
From: Bernhard Beschow <shentey@gmail.com>

This is a follow-up on patch "malta: Move PCI interrupt handling from
gt64xxx_pci to piix4" where i8259[] was moved from MaltaState to
PIIX4State to make the code movement more obvious. However, i8259[]
seems redundant to *isa, so remove it.
