[PATCH] Fixes Mayflash 4-port Gamecube adapter's PC mode

[PATCH] Fixes Mayflash 4-port Gamecube adapter's PC mode

[Calvin Cochran]

From: Calvin Cochran <cochran.calvin@gmail.com>

Enabling HID_QUIRK_MULTI_INPUT allows the adapter to correctly report
its 4 joystick inputs and stops it from acting like a mouse.

This patch was originially submitted by Andrew Rodland on
04 February 2015, but upon cursory inspection of the mailing list
archives, it seems no one ever followed up on it. If there's something
I need to do to make sure he gets credit for the patch, please let
me know. Thanks!
