Building ppc40x_defconfig throws the following error:
CC arch/powerpc/kernel/traps.o
arch/powerpc/kernel/traps.c:2232:29: warning: no previous prototype for
'WatchdogHandler' [-Wmissing-prototypes]
2232 | void __attribute__ ((weak)) WatchdogHandler(struct pt_regs *regs)
| ^~~~~~~~~~~~~~~
This function was imported by commit 14cf11af6cf6 ("powerpc: Merge
enough to start building in arch/powerpc.") as a weak function but
never defined and/or called outside traps.c
As it has only one caller fold it inside its caller and remove it.
