Subject: [PATCH] of: property: Make 'no port node found' output a debug
|
|
message
|
|
|
|
There are cases where an unavailable port is not an error, making this
|
|
error message a false-positive. Since commit d56de8c9a17d8 ("usb: typec:
|
|
tcpm: try to get role switch from tcpc fwnode") the role switch is tried
|
|
on the port dev first and tcpc fwnode afterwards. If using the latter
|
|
bindings getting from port dev fails every time. The kernel log is flooded
|
|
with the messages like:
|
|
OF: graph: no port node found in /soc@0/bus@42000000/i2c@42530000/usb-typec@50
|
|
Silence this message by making it a debug message.
