platform/x86: hp-wmi: Fix detection for dock and tablet mode
commit 298747b7579f5bbbced793d997b333fd10a24921 upstream.
The current driver code is not checking for the error values returned by
'hp_wmi_dock_state()' and 'hp_wmi_tablet_state()' before passing the
returned values down to 'input_report_switch()'. This error code is
being translated to '1' in the input subsystem, reporting the wrong
status.
The biggest problem caused by this issue is that several laptops are
wrongly reported by the driver as docked, preventing them to be put to
sleep using the LID (and in most cases they are not even dockable).
With this patch we create the report switches only if we are able to
read the dock and tablet mode status correctly from ACPI.
