Description
In the Linux kernel, the following vulnerability has been resolved: phy: ti: phy-omap-usb2: Fix NULL pointer dereference for SRP If the external phy working together with phy-omap-usb2 does not implement send_srp(), we may still attempt to call it. This can happen on an idle Ethernet gadget triggering a wakeup for example: configfs-gadget.g1 gadget.0: ECM Suspend configfs-gadget.g1 gadget.0: Port suspended. Triggering wakeup ... Unable to handle kernel NULL pointer dereference at virtual address 00000000 when execute ...

For USB peripheral only cases these both could be NULL.
