Hi, this is a patchset with small fixes for improving the USB-audio mixer behavior. Instead of treating the error from a control message continuously, initialize all at the probe and keep the rest working. The first two patches are rather fixes for error messages in get_ctl_value_v2() function, the last one implements the new behavior.
