Subject: KVM: use KVM_CAP_IRQ_ROUTING to protect the routing related code
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=9900b4b48b095895cf962054e45aafa49ef70f74;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

KVM: use KVM_CAP_IRQ_ROUTING to protect the routing related code

The KVM code sometimes uses CONFIG_HAVE_KVM_IRQCHIP to protect
code that is related to IRQ routing, which not all in-kernel
irqchips may support.

Use KVM_CAP_IRQ_ROUTING instead.
