If anyone has any objections, please let me know. ------------------ From: Takashi Iwai [ Upstream commit a154f7b9f197b3d5e41fa3ad62083f5aa93b1fe8 ] Faaris reported a problem with Audient EVO4 device and it turned out to be a regression by the recent fix commit 87a6f2fa6e6c ("ALSA: usb-audio: Propagate write errors in generic mixer put callbacks"). It exhibited that the hardware gives errors at accessing the mixer unit 10 on certain channels, and the change above made it a fatal error. We had already a quirk for Audient iD14 to work around such errors from the mixer controls, and we can simply apply the same for EVO4. OTOH, it's highly possible that other Audient devices suffer from the same issue; they must be using similar firmware, after all. So, in this patch, we apply the quirk generically to all devices with the vendor ID Audient (2708), instead. Ignoring the control error isn't usually less critical than overreaction to the firmware misbehavior.
