[PATCH 0/3] hid: sony: Fix duplicate check logic and other cleanups

This set of patches fixes a case where the duplicate check incorrectly
rejects valid devices and cleans up the behavior when a DualShock 3 is
initially connected.  It also adds a bit of documentation regarding the
DualShock 4 reporting rate as there have been a few cases where users
needed to slow it down since the full rate can be too much for some
slow embedded devices.
