Subject: [PATCH] ASoC: simple-card: Add snd_card's name parsing from DT node
support
If the DT is used and the CPU DAI device has only one DAI, the card
name will be like :
ALSA device list:
0: 40031000.sai-sgtl5000
And this name maybe a little ugly to some customers, so here the
card name parsing from DT node is supported.
