Subject: [PATCH] HID: quirks: Add no_init_reports for AKAI midi controller
Date: Wed, 27 Jan 2016 23:09:37 +0900	[thread overview]
Message-ID: <1453903777-11790-1-git-send-email-shorne@gmail.com> (raw)

The midi controller times-out while initializing reports, this
causes boot to take an extra 10 seconds. The device descriptor
advertises that it has an internal HID device but seems to not
actually do anything useful.
