If anyone has any objections, please let me know. ------------------ From: Geoffrey D. Bennett [ Upstream commit 8780f561f6717dec52351251881bff79e960eb46 ] The Focusrite Scarlett 2i2 1st Gen (1235:8006) produces distorted/silent audio when QUIRK_FLAG_SKIP_IFACE_SETUP is active, as that flag causes the feedback format to be detected as 17.15 instead of 16.16. Add a DEVICE_FLG entry for this device before the Focusrite VENDOR_FLG entry so that it gets no quirk flags, overriding the vendor-wide SKIP_IFACE_SETUP. This device doesn't have the internal mixer, Air, or Safe modes that the quirk was designed to protect.
