Subject: hw/isa/lpc_ich9: Unexport PIRQ functions
X-Git-Tag: v8.0.0-rc0~41^2~85
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=29a457cbbc90a9938f8ca3d6bf397e99b9559e58;p=thirdparty%2Fqemu.git

hw/isa/lpc_ich9: Unexport PIRQ functions

No need to rely on the board to wire up the ICH9 PCI IRQs. All functions
access private state of the LPC device which suggests that it should
wire up the IRQs.
