Subject: [PATCH v6 04/12] ASoC: qcom: lpass-platform: fix memory leak
Date: Fri, 14 Aug 2020 16:23:00 +0530
Message-ID: <1597402388-14112-5-git-send-email-rohitkr@codeaurora.org> (raw)
In-Reply-To: <1597402388-14112-1-git-send-email-rohitkr@codeaurora.org>

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")
