Subject: [PATCH] usb: host: dwc2: add trace to have clean usb start
Solve issue for the display of "usb start" command on stm32mp1
because one carriage return is missing in DWC2 probe.
Before the patch:
STM32MP> usb start
starting USB...
Bus usb-otg@49000000: Bus usbh-ehci@5800d000: USB EHCI 1.00
after the patch:
STM32MP> usb start
starting USB...
Bus usb-otg@49000000: USB DWC2
Bus usbh-ehci@5800d000: USB EHCI 1.00
