Subject: hw/isa/piix4: Convert reset handler to DeviceReset
X-Git-Tag: v4.2.0-rc0~52^2~13
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=fd52c20f2c58152f6f23bed658474ae1d1a2fe52;p=thirdparty%2Fqemu.git

hw/isa/piix4: Convert reset handler to DeviceReset

The PIIX4/ISA is a PCI device within the PIIX4 chipset, it will be reset
when the PCI bus it stands on is reset.

Convert its reset handler into a proper Device reset method.
