Currently driver looks for the highest revision of usb audio class protocol version from the configuration summary descriptors. Instead, select first device preferred configuration not supporting full UAC 3.0 as full UAC 3.0 is not currently supported by audio class driver. Also, rename audio function subclass FULL_ADC_PROFILE to FULL_ADC_3_0 as defined in spec. Change-Id: I656e3f34e9f68530b886fd55ff2541318405fd2c Signed-off-by: Hemant Kumar <hemantk@codeaurora.org>
