Subject: usb-uhci: update irq line on reset
X-Git-Tag: v1.1-rc0~33^2
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=aba1f242834a4365ca3250cd4d14226d66e77ed5;p=users%2Fdwmw2%2Fqemu.git

usb-uhci: update irq line on reset

uhci_reset() clears irq mask and irq status registers, but doesn't
update the irq line.  Which may result in suspious IRQs after uhci
reset.  Fix it.
