[PATCH v4 05/24] ASoC: renesas: rz-ssi: Use only the proper amount of dividers
From: Claudiu
Date: Tue Dec 10 2024 - 12:18:13 EST
From: Claudiu Beznea <claudiu.beznea.uj@xxxxxxxxxxxxxx>
There is no need to populate the ckdv[] with invalid dividers as that
part will not be indexed anyway. The ssi->audio_mck/bclk_rate should
always be >= 0. While at it, change the ckdv type as u8, as the divider
128 was previously using the s8 sign bit.

Changes in v4:
- changed the ckdv type from s8 to u8 and updated patch description
to reflect it

- s/sh/renesas in patch title
Changes in v2:
- none
