Summary
phy: usb: sunplus: Fix potential null-ptr-deref in sp_usb_phy_probe()
Details

In the Linux kernel, the following vulnerability has been resolved:

phy: usb: sunplus: Fix potential null-ptr-deref in spusbphy_probe()

spusbphyprobe() will call platformgetresourcebyname() that may fail and return NULL. devmioremap() will use usbphy->moon4resmem->start as input, which may causes null-ptr-deref. Check the ret value of platformgetresourcebyname() to avoid the null-ptr-deref.
