From: Arnd Bergmann <arnd@xxxxxxxx> The tegra186_mc_client_sid_override() is only called from an #ifdef block: drivers/memory/tegra/tegra186.c:74:13: error: 'tegra186_mc_client_sid_override' defined but not used [-Werror=unused-function] 74 | static void tegra186_mc_client_sid_override(struct tegra_mc *mc, | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Add another #ifdef around the called function.
