[PATCH 4.19 072/264] ASoC: qcom: lpass-platform: fix memory leak

[Greg Kroah-Hartman]

From: Rohit kumar <rohitkr@xxxxxxxxxxxxxx>

[ Upstream commit 5fd188215d4eb52703600d8986b22311099a5940 ]

lpass_pcm_data is never freed. Free it in close
ops to avoid memory leak.

Fixes: 022d00ee0b55 ("ASoC: lpass-platform: Fix broken pcm data usage")
