[PULL 31/35] target/ppc: Fix the order of kvm_enable judgment about kvmppc_set_interrupt()
Posted by Cédric Le Goater 1 year, 2 months ago
From: jianchunfu <chunfu.jian@shingroup.cn>

It's unnecessary for non-KVM accelerators(TCG, for example),
to call this function, so change the order of kvm_enable() judgment.

The static inline function that returns -1 directly does not work
 in TCG's situation.
