Log results of failed EC commands to identify a problem more easily.
Replace cros_ec_cmd_xfer_status with cros_ec_cmd_xfer because the result has already been checked in this function. The wrapper is not needed.
Alternatively, you can still use cros_ec_cmd_xfer_status( ). I guess it is okay to have 2 logs for an error.

I am thinking of if it is a better solution to print msg->result here.
goto error;
if (msg->result != EC_RES_SUCCESS) {dev_err(ec_dev->dev, "Command %d failed: %d\n", cmd,msg->result);ret = -EPROTO;goto error;}
So that you don't need this block.
