Subject[PATCH 19/21] powerpc: Add missing prototypes for hw_breakpoint_handler & arch_unregister_hw_breakpoint
Date
In commit 5aae8a537080 ("powerpc, hw_breakpoints: Implement hw_breakpoints
for 64-bit server processors") function hw_breakpoint_handler and
arch_unregister_hw_breakpoint were added without function prototypes in
hw_breakpoint.h header.

Fix the following warning(s) (treated as error in W=1):

AR init/built-in.o
arch/powerpc/kernel/hw_breakpoint.c:106:6: error: no previous prototype for ‘arch_unregister_hw_breakpoint’ [-Werror=missing-prototypes]
void arch_unregister_hw_breakpoint(struct perf_event *bp)
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~
arch/powerpc/kernel/hw_breakpoint.c:209:5: error: no previous prototype for ‘hw_breakpoint_handler’ [-Werror=missing-prototypes]
int hw_breakpoint_handler(struct die_args *args)
^~~~~~~~~~~~~~~~~~~~~
cc1: all warnings being treated as errors
