[ Upstream commit 6d5e7af1f6f5924de5dd1ebe97675c2363100878 ]
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")
