Subject[PATCH 3.16 147/233] HID: add quirk for Akai MIDImix.
3.16.48-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: "Steinar H. Gunderson" <sgunderson@bigfoot.com>

commit 4973ca9a01e2354b159acedec1b9b8eb8de02ab7 upstream.

The Akai MIDImix (09e8:0031) is a MIDI fader controller that speaks
regular MIDI and works well with Linux. However, initialization gets
delayed due to reports timeout:

[3643645.631124] hid-generic 0003:09E8:0031.0020: timeout initializing reports
[3643645.632416] hid-generic 0003:09E8:0031.0020: hiddev0: USB HID v1.11 Device [AKAI MIDI Mix] on usb-0000:00:14.0-2/input0

Adding "usbhid.quirks=0x09e8:0x0031:0x20000000" on the kernel
command line makes the issues go away.
