From c8cd751060b149997b9de53a494fb1490ded72c5 Mon Sep 17 00:00:00 2001 From: Petr Cvek Date: Tue, 7 Mar 2017 00:57:20 +0100 Subject: [PATCH] usb: gadget: uvc: Missing files for configfs interface 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.
