In the Linux kernel, the following vulnerability has been resolved:
net: ethernet: stmmac: fix altrtsepcs function when using a fixed-link
When using a fixed-link, the altrtsepcs driver crashes due to null-pointer dereference as no phydevice is provided to tsepcsfixmacspeed function. Fix this by adding a check for phydev before calling the tsepcsfixmacspeed() function.
Also clean up the tsepcsfixmacspeed function a bit. There is no need to check for splitterbase and sgmiiadapter_base because the driver will fail if these 2 variables are not derived from the device tree.
