Subject: [PATCH v6 06/12] ASoC: qcom: lpass-cpu: fix concurrency issue
Date: Fri, 14 Aug 2020 16:23:02 +0530 [thread overview]
Message-ID: <1597402388-14112-7-git-send-email-rohitkr@codeaurora.org> (raw)
In-Reply-To: <1597402388-14112-1-git-send-email-rohitkr@codeaurora.org>
i2sctl register value is set to 0 during hw_free(). This
impacts any ongoing concurrent session on the same i2s
port. As trigger() stop already resets enable bit to 0,
there is no need of explicit hw_free. Removing it to
fix the issue.
Fixes: 80beab8e1d86 ("ASoC: qcom: Add LPASS CPU DAI driver")
