[alsa-devel] [PATCH] ASoC: rsnd: ssi: 24bit data needs right-aligned settings

[Kuninori Morimoto]

From: Kuninori Morimoto <kuninori.morimoto.gx at renesas.com>

Data left/right aligned is controlled by PDTA bit on SSICR.
But default is left-aligned. Thus 24bit sound will be very small sound
without this patch.
