3.16.84-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Johan Hovold johan@kernel.org
commit 3139b180906af43bc09bd3373fc2338a8271d9d9 upstream.
Make sure to use the current alternate setting when verifying the interface descriptors to avoid binding to an invalid interface.
Failing to do so could cause the driver to misbehave or trigger a WARN() in usb_submit_urb() that kernels with panic_on_warn set would choke on.
