Subject: MIPS: KVM: Uninit VCPU in vcpu_create error path
From: James Hogan <[email protected]>
commit 585bb8f9a5e592f2ce7abbe5ed3112d5438d2754 upstream.
If either of the memory allocations in kvm_arch_vcpu_create() fail, the vcpu which has been allocated and kvm_vcpu_init'd doesn't get uninit'd in the error handling path. Add a call to kvm_vcpu_uninit() to fix this.
