ASoC: sti: set player private data
Set substream player private data. substream player private data is used in uni_player_irq_handler to lock, stop & unlock the stream when interrupt indicates underflow/overflow. If not set, then segmentation fault occurs. Signed-off-by: Moise Gergaud <moise.gergaud@st.com> Acked-by: Arnaud Pouliquen <arnaud.pouliquen@st.com> Signed-off-by: Mark Brown <broonie@kernel.org>
