usb: typec: ucsi: Invoke ucsi_run_command tracepoint
The ucsi_run_command trace event is exposed in tracefs, but it never produces any output because the UCSI core never invokes the associated tracepoint. As a result, enabling the event under events/ucsi/ yields no traces, preventing users from inspecting UCSI command sequencing. Wire the tracepoint into the UCSI command path so that commands are properly reported. Example: 50.692342: ucsi_run_command: GET_CONNECTOR_STATUS -> OK (err=0) 50.692345: ucsi_connector_change: port0 status: change=4800, ... 51.750298: ucsi_run_command: GET_CABLE_PROPERTY -> FAIL (err=-5) 51.773360: ucsi_run_command: GET_CONNECTOR_STATUS -> OK (err=0) Signed-off-by: Loic Poulain <loic.poulain@oss.qualcomm.com> Reviewed-by: Heikki Krogerus <heikki.krogerus@linux.intel.com> Link: https://patch.msgid.link/20260217103403.1956-1-loic.poulain@oss.qualcomm.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
