4.2-stable review patch. If anyone has any objections, please let me know.
------------------
From: Hans de Goede <hdegoede@xxxxxxxxxx>
commit f4513b065f7dbd37224226ef6e44b09eff742776 upstream.
is_extcon_changed should only check the idx-th bit of new, not
the entirety of new when setting attached.
This fixes extcon sending notifications that a cable was inserted when
it gets removed while another cable is still connected.
