Subject: [PATCH] soundwire: debugfs: use controller id instead of link_id
Date: Fri, 15 Jan 2021 16:25:59 +0000 [thread overview]
Message-ID: <20210115162559.20869-1-srinivas.kandagatla@linaro.org> (raw)
link_id can be zero and if we have multiple controller instances
in a system like Qualcomm debugfs will end-up with duplicate namespace
resulting in incorrect debugfs entries.
Using id should give a unique debugfs directory entry and should fix below
warning too.
"debugfs: Directory 'master-0' with parent 'soundwire' already present!"
Fixes: bf03473d5bcc ("soundwire: add debugfs support")
