[PATCH] usb: i.MX: improve regulator handling

[Uwe Kleine-König]

Instead of just ignoring errors related to regulator getting error out.
In case there is no regulator in the device tree, regulator_get() returns
the dummy regulator and not an error code, so the change is right for
this situation, too.
