[PATCH] KVM: x86: Redundant variable assignments can be merged

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



When reading kvm code, find the 'r' variable declaration
and then assign the value in kvm_vm_ioctl_get_irqchip and
kvm_vm_ioctl_set_irqchip function, It can be combined into one sentence.
