[PATCH 4.4 29/63] watchdog: hpwdt: fix unused variable warning

From: Greg Kroah-Hartman
Date: Fri Mar 16 2018 - 13:30:38 EST


4.4-stable review patch. If anyone has any objections, please let me know.

------------------

From: Arnd Bergmann <arnd@xxxxxxxx>

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.
