commit c8cd751060b149997b9de53a494fb1490ded72c5 upstream.
Commit 76e0da34c7ce ("usb-gadget/uvc: use per-attribute show and store methods") caused a stringification of an undefined macro argument "aname", so three UVC parameters (streaming_interval, streaming_maxpacket and streaming_maxburst) were named "aname".
Add the definition of "aname" to the main macro and name the filenames as originaly intended.

What stable kernel(s) do you want this applied to?

The commit 76e0da34c7ce which causes the regression is introduced in v4.4, so I would think this patch have to be applied down to v4.4.

FYI, I tested this patch on v4.4 and v4.9.

Thanks,
-Bin.
