| |
The unsigned expression compared with zero `target < 0' is unneeded and its result is always false. we can also check the target's value returned from `kvm_target_cpu' is one of the KVM_* macros, and these macros are defined greater than or equal to 0. Therefore, the comparison code block: if (target < 0) return -ENODEV; is unneeded. We can safely remove it.
