hp-wmi: remove a variable that is never read
Anssi Hannula [Sun, 20 Feb 2011 18:07:21 +0000 (20:07 +0200)]
Remove the status variable from hp_wmi_perform_query which holds the
return value from wmi_evaluate_method(). It is never checked as the
function bails out if the output buffer hasn't been allocated which
indicates the call failed.
