Commit fe8abf332b8f ("usb: dwc3: support clocks and resets for DWC3 core")
adds support for handling clocks and resets in the DWC3 core, so that for
platforms following the standard devicetree bindings this does not need
to be duplicated in all the different glue layers.
These changes intended for devicetree based platforms introduce an
uncoditional clk_bulk_get() in the core probe path. This leads to the
following error being logged on x86/ACPI systems:
[ 26.276783] dwc3 dwc3.3.auto: Failed to get clk 'ref': -2
This commits wraps the clk_bulk_get() in an if (dev->of_node) check so
that it only is done on devicetree instantiated devices, fixing this
error.
