Dan Carpenter fb9d513cdf phy: stm32-usphyc: Fix off by one in probe() 
[ Upstream commit cabd25b572 ]

The "index" variable is used as an index into the usbphyc->phys[] array
which has usbphyc->nphys elements.  So if it is equal to usbphyc->nphys
then it is one element out of bounds.  The "index" comes from the
device tree so it's data that we trust and it's unlikely to be wrong,
however it's obviously still worth fixing the bug.  Change the > to >=.
