Include appropriate header file acutils.h in acpica/utstate.c because function acpi_ut_create_pkg_state_and_push() has its prototype declaration in acutils.h. Also, encloses the function in acpica/utstate.c in ifdef condition of ACPI_FUTURE_USAGE. This eliminates the following warning in utstate.c: drivers/acpi/acpica/utstate.c:64:1: warning: no previous prototype for ‘acpi_ut_create_pkg_state_and_push’ [-Wmissing-prototypes] Signed-off-by: Rashika Kheria <rashika.kheria@xxxxxxxxx> Reviewed-by: Josh Triplett <josh@xxxxxxxxxxxxxxxx> --- drivers/acpi/acpica/utstate.c | 3 +++ 1 file changed, 3 insertions(+) diff --git a/drivers/acpi/acpica/utstate.c b/drivers/acpi/acpica/utstate.c index 03c4c2f..0920d23 100644 --- a/drivers/acpi/acpica/utstate.c +++ b/drivers/acpi/acpica/utstate.c @@ -43,6 +43,7 @@ #include <acpi/acpi.h> #include "accommon.h" +#include "acutils.h" #define _COMPONENT ACPI_UTILITIES ACPI_MODULE_NAME("utstate") @@ -60,6 +61,7 @@ ACPI_MODULE_NAME("utstate") * DESCRIPTION: Create a new state and push it * ******************************************************************************/ +#ifdef ACPI_FUTURE_USAGE acpi_status acpi_ut_create_pkg_state_and_push(void *internal_object, void *external_object, @@ -79,6 +81,7 @@ acpi_ut_create_pkg_state_and_push(void *internal_object, acpi_ut_push_generic_state(state_list, state); return (AE_OK); } +#endif /******************************************************************************* * -- 1.7.9.5 -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
