Subject: usb: chipidea: imx: avoid EPROBE_DEFER printed as error
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=d3d8425a21ed1b14bc896f827ee495e06bff2504;p=deliverable%2Flinux.git

usb: chipidea: imx: avoid EPROBE_DEFER printed as error

Avoid printing an error if adding the device failes with return
value EPROBE_DEFFER. This may happen e.g. due to missing GPIO for
the vbus-supply regulator.
