ASoC: sun8i-codec-analog: split out line in
Allwinner V3s features an analog codec without LINEIN. Split out this part, in order to prepare for the V3s analog codec. Signed-off-by: Icenowy Zheng <icenowy@aosc.xyz> Acked-by: Chen-Yu Tsai <wens@csie.org> Signed-off-by: Mark Brown <broonie@kernel.org>
