Arnd Bergmann abdfde0377 samples/hw_breakpoint: fix building without module unloading ... [ Upstream commit b9080468ca ] __symbol_put() is really meant as an internal helper and is not available when module unloading is disabled, unlike the previously used symbol_put(): samples/hw_breakpoint/data_breakpoint.c: In function 'hw_break_module_exit': samples/hw_breakpoint/data_breakpoint.c:73:9: error: implicit declaration of function '__symbol_put'; did you mean '__symbol_get'? [-Werror=implicit-function-declaration] The hw_break_module_exit() function is not actually used when module unloading is disabled, but it still causes the build failure for an undefined identifier. Enclose this one call in an appropriate #ifdef to clarify what the requirement is. Leaving out the entire exit function would also work but feels less clar in this case.
