While it can be slightly beneficial for the build performance to use forward declarations instead of includes, the handling of them together with changes in the included headers makes it unnecessary complicated and fragile. Just replace them with actual includes since some parts (hwmon, ..) of the kernel even request avoidance of forward declarations and net/ is mostly not using them in *.c file.
