phy: phy-sun4i-usb: Fix optional gpios failing probe
The interrupt 0 is not a valid interrupt number. In the event where the retrieval of the vbus-det gpio would return null, the gpiod_to_irq callback would return 0, while the current code makes the assumption that it is a valid interrupt, and would go on calling request_irq. Obviously, this would fail, preventing the driver from probing properly, while the vbus and id gpios are optional. Signed-off-by:Quentin Schulz <quentin.schulz@free-electrons.com> Signed-off-by:
