Re: [PATCH] samples/hw_breakpoint: Fix kernel BUG 'invalid opcode: 0000'

Hi Luis

The 'kernel test robot' report an error [0]:

	>> samples/hw_breakpoint/data_breakpoint.c:73:2: error: call to undeclared function '__symbol_put'; 
	ISO C99 and later do not support implicit function declarations [-Werror,-Wimplicit-function-declaration]
	           __symbol_put(ksym_name);
	           ^
	   samples/hw_breakpoint/data_breakpoint.c:73:2: note: did you mean '__symbol_get'?
	   include/linux/module.h:301:7: note: '__symbol_get' declared here
	   void *__symbol_get(const char *symbol);
	         ^
	   1 error generated.

Do I need to do something? It seems that no changes need to be made from the
mainline code.
