Subject: [PATCH] Asoc: qcom: lpass-platform: Fix memory leak
Date:   Sun, 15 Nov 2020 10:26:50 +0530
Message-Id: <1605416210-14530-1-git-send-email-srivasam@codeaurora.org>
Precedence: bulk

lpass_pcm_data is not freed in error paths. Free it in
error paths to avoid memory leak.

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