| Message-ID | <unXcB-3OU-11@gated-at.bofh.it> |
3.16.48-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Stafford Horne <shorne@gmail.com>
commit a382c30c662a31dd8f51cc4b6dad82d39205d50c upstream.
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.
