[PATCH 3.2 60/94] usb: quirks: add quirk for WORLDE MINI MIDI keyboard

From: Ben Hutchings
Date: Thu Dec 28 2017 - 13:22:08 EST


3.2.97-rc1 review patch. If anyone has any objections, please let me know.

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

From: Felipe Balbi <felipe.balbi@xxxxxxxxxxxxxxx>

commit 2811501e6d8f5747d08f8e25b9ecf472d0dc4c7d upstream.

This keyboard doesn't implement Get String descriptors properly even
though string indexes are valid. What happens is that when requesting
for the String descriptor, the device disconnects and
reconnects. Without this quirk, this loop will continue forever.
