If anyone has any objections, please let me know. ------------------ From: Arnd Bergmann commit aeebc6ba88ba3758ad95467ff6191fabf2074c13 upstream. The new hpwdt_my_nmi() function is used conditionally, which produces a harmless warning in some configurations: drivers/watchdog/hpwdt.c:478:12: error: 'hpwdt_my_nmi' defined but not used [-Werror=unused-function] This moves it inside of the #ifdef that protects its caller, to silence the warning.
