Subject[PATCH] powerpc: Mark the variable earlycon_acpi_spcr_enable maybe_unused
Date
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
