Hi Geert, Just to let you know, this warning is already fixed by a pending patch I've sent two weeks ago: https://lkml.org/lkml/2018/3/20/424.

drivers/phy/st/phy-stm32-usbphyc.c: In function ‘stm32_usbphyc_probe’: drivers/phy/st/phy-stm32-usbphyc.c:364: warning: ‘i’ may be used uninitialized in this function Indeed, during the first loop iteration, "i" is uninitialized. However, "i" does not represent the intended PHY instance number to print. Fix this by printing the correct variable instead.
