Subject[PATCH] HID: sony: Enable Gasia third-party PS3 controllers, v2
Without this, my "Gasia Co.,Ltd PS(R) Gamepad" would not send
any events. Now everything works including the leds.

Based on work by Andrew Haines and Antonio Ospite.

v2:
- edited error messages
- use output_report

Despite Andrew's report, using output_report worked fine.
