Subject: Unplugging USB-C charger cable causes `ucsi_acpi USBC000:00:
 ucsi_handle_connector_change: ACK failed (-110)`

Dear Linux folks,


On the Dell XPS 13, BIOS 2.21.0 06/02/2022, with Debian sid/unstable and 
Linux 6.5.10, when unplugging the (Dell) USB Type-C charger cable, Linux 
logs the error below:

     ucsi_acpi USBC000:00: ucsi_handle_connector_change: ACK failed (-110)

As this is logged with level error, can this be somehow fixed?

     drivers/usb/typec/ucsi/ucsi.c: dev_err(ucsi->dev, "%s: ACK failed 
(%d)", __func__, ret);

Please find the output of `dmesg` attached.


Kind regards,

Paul
