Not a big deal, but I'm happy if we can use same naming rule
for same things.
rtd->dai_link->symmetric_samplebits;
^^^^^^^^^^
dai->driver->symmetric_samplebits;
^^^^^^^^^^
cpu_dai->sample_bits
^^^^^^^^^^^
__soc_pcm_params_symmetry(rate, rates);
^^^^^ ^^^^^
__soc_pcm_params_symmetry(sample_bits, samplebits);
^^^^^^^^^^^ ^^^^^^^^^^
Thank you for your help !!
Best regards
