usb: typec: mux: Remove the use of dev_err_probe()

[PATCH] usb: typec: mux: Remove the use of dev_err_probe()

Posted by Xichao Zhao 1 month, 2 weeks ago

The dev_err_probe() doesn't do anything when error is '-ENOMEM'.
Therefore, remove the useless call to dev_err_probe(), and just
return the value instead.
