Shanker Donthineni d408d23add KVM: arm/arm64: vgic: Stop injecting the MSI occurrence twice commit `0bdbf3b071` upstream. The IRQFD framework calls the architecture dependent function twice if the corresponding GSI type is edge triggered. For ARM, the function kvm_set_msi() is getting called twice whenever the IRQFD receives the event signal. The rest of the code path is trying to inject the MSI without any validation checks. No need to call the function vgic_its_inject_msi() second time to avoid an unnecessary overhead in IRQ queue logic. It also avoids the possibility of VM seeing the MSI twice. Simple fix, return -1 if the argument 'level' value is zero.
