Subject: [PATCH] ASoC: q6routing: initialize data correctly
Date: Mon, 3 Sep 2018 12:07:47 +0100 [thread overview]
Message-ID: <20180903110747.10745-1-srinivas.kandagatla@linaro.org> (raw)
Some of the router data fields are left as default zeros which are
valid dai ids, so initialize these to invalid value of -1.
Without intializing these correctly get_session_from_id() can return
incorrect session resulting in not closing the opened copp and messing
up with the copp ref count.
Fixes: e3a33673e845 ("ASoC: qdsp6: q6routing: Add q6routing driver")
