powerpc: Mark the variable earlycon_acpi_spcr_enable maybe_unused
Re-use the object-like macro EARLYCON_USED_OR_UNUSED to mark `earlycon_acpi_spcr_enable` as maybe_unused. Fix the following warning (treated as error in W=1) CC arch/powerpc/kernel/setup-common.o In file included from ./include/linux/serial_8250.h:14:0, from arch/powerpc/kernel/setup-common.c:33: ./include/linux/serial_core.h:382:19: error: ‘earlycon_acpi_spcr_enable’ defined but not used [-Werror=unused-const-variable=] static const bool earlycon_acpi_spcr_enable; ^~~~~~~~~~~~~~~~~~~~~~~~~ cc1: all warnings being treated as errors Signed-off-by: Mathieu Malaterre <malat@debian.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
