Subject: [PATCH 2/2] net: dsa: vsc73xx: Return an error code as a constant in
 vsc73xx_platform_probe()

* Return an error code without storing it in an intermediate variable.

* Delete the local variable “ret” which became unnecessary
  with this refactoring.

This issue was detected by using the Coccinelle software.
