If anyone has any objections, please let me know. ------------------ From: Geoffrey D. Bennett [ Upstream commit a8cc55bf81a45772cad44c83ea7bb0e98431094a ] Remove QUIRK_FLAG_VALIDATE_RATES for Focusrite. With the previous commit, focusrite_valid_sample_rate() produces correct rate tables without USB probing. QUIRK_FLAG_VALIDATE_RATES sends SET_CUR requests for each rate (~25ms each) and leaves the device at 192kHz. This is a problem because that rate: 1) disables the internal mixer, so outputs are silent until an application opens the PCM and sets a lower rate, and 2) the Air and Safe modes get disabled.
