-Subject: [PATCH] sound: Support for Dion Audio LOCO-V2 DAC-AMP HAT
-
-Signed-off-by: Miquel Blauw <info@dionaudio.nl>
-
-ASoC: dionaudio_loco-v2: fix S24_LE format
-
-Remove set_bclk_ratio call so 24-bit data is transmitted in
-24 bclk cycles.
-
-Also remove hw_params and ops as they are no longer needed.
