Re: [PATCH] powerpc/ptrace: Add prototype for function pt_regs_check

`pt_regs_check` is a dummy function, its purpose is to break the build
if struct pt_regs and struct user_pt_regs don't match.

This function has no functionnal purpose, and will get eliminated at
link time or after init depending on CONFIG_LD_DEAD_CODE_DATA_ELIMINATION

This commit adds a prototype to fix warning at W=1:

  arch/powerpc/kernel/ptrace.c:3339:13: error: no previous prototype for ���pt_regs_check��� [-Werror=missing-prototypes]

Applied to powerpc next, thanks.
