ALSA: usb-audio: Apply IGNORE_CTL_ERROR quirk to all Audient devices
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.
