If anyone has any objections, please let me know. ------------------ From: Petr Cvek 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.
