Shouldn't the patch also capture the current audio rate in tda998x_codec.c:tda_hw_params?  Otherwise, when tda998x_drv.c:tda998x_audio_start invokes tda998x_drv.c:tda998x_configure_audio, the value of 'N' will be calculated incorrectly.

So something similar to:

diff --git a/drivers/gpu/drm/i2c/tda998x_codec.c b/drivers/gpu/drm/i2c/tda998x_codec.c
