From 88abb8eff494d0be7819e744e74d62d5bc852905 Mon Sep 17 00:00:00 2001 From: Eldad Zack Date: Sat, 3 Aug 2013 10:51:14 +0200 Subject: [PATCH] ALSA: usb-audio: remove implicit_fb from quirk Since the quirks all apply to implicit feedback (the source endpoint is always a data endpoint), there's no need to set and check a flag for it.
