nios2: Fix unused variable warning
Fix the following compiler splat by adding __maybe_unused annotation to the variable. Using this particular annotation has the least ugly impact on the code compared to using ifdeffery. arch/nios2/kernel/setup.c: In function 'nios2_boot_init': arch/nios2/kernel/setup.c:107:7: warning: unused variable 'cmdline_passed' [-Wunused-variable] char cmdline_passed[COMMAND_LINE_SIZE] = { 0, }; ^ Signed-off-by: Marek Vasut <marex@denx.de> Acked-by: Ley Foon Tan <lftan@altera.com>
