From 824818b148db42173446707df4cbd61cd7133272 Mon Sep 17 00:00:00 2001 From: Clemens Ladisch Date: Thu, 4 Aug 2011 16:17:42 +0200 Subject: ALSA: snd-usb: Accept UAC2 FORMAT_TYPE descriptors with bLength > 6 The Focusrite Scarlett 18i6 USB has them that way, which is probably a bug. Anyway, the driver should simply ignore this fact.
