Subject: platform/x86: hp-wmi: Fix error value for hp_wmi_tablet_state
From: Carlo Caione <carlo@xxxxxxxxxxxx>
commit c7dfc2facbd69dad89b75e13c608da709668dcd0 upstream.
hp_wmi_tablet_state() fails to return the correct error code when
hp_wmi_perform_query() returns the HP WMI query specific error code
that is a positive value.
