[PATCHv4] HID: sony: Enable Gasia third-party PS3 controllers

From: Lauri Kasanen
Date: Mon Feb 16 2015 - 08:05:02 EST


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.

Antonio: size 8 works.

v4:
- use size 8

v3:
- reuse the dummy heap buffer
- skip later checks if the earlier ones fail

v2:
- edited error messages
- use output_report
