    KVM: no need to check return value of debugfs_create functions · 3e7093d0
    Greg KH authored
    When calling debugfs functions, there is no need to ever check the
    return value.  The function can work or not, but the code logic should
    never do something different based on this.
    
    Also, when doing this, change kvm_arch_create_vcpu_debugfs() to return
    void instead of an integer, as we should not care at all about if this
    function actually does anything or not.
