[PATCH] ASoC: amd: raven: Fix memory leak in acp3x_dma_close()

[phucduc . bui]

From: bui duc phuc <phucduc.bui@xxxxxxxxx>

acp3x_dma_open() allocates a struct i2s_stream_instance for
each substream, but acp3x_dma_close() never frees it, leaking
it on every open/close cycle.

Free it in acp3x_dma_close().

Fixes: 9f7041b71a2f ("ASoC: amd: closing specific instance.")
