patch "usb: quirks: add quirk for WORLDE MINI MIDI keyboard" added to usb-linus

This is a note to let you know that I've just added the patch titled

usb: quirks: add quirk for WORLDE MINI MIDI keyboard

to my usb git tree which can be found at
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git
in the usb-linus branch.

The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.)

The patch will hopefully also be merged in Linus's tree for the next -rc kernel release.

If you have any questions about this process, please let me know.

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.
