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 --- arch/nios2/kernel/setup.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/arch/nios2/kernel/setup.c b/arch/nios2/kernel/setup.c index b101a43..a4ff86d 100644 --- a/arch/nios2/kernel/setup.c +++ b/arch/nios2/kernel/setup.c @@ -104,7 +104,7 @@ asmlinkage void __init nios2_boot_init(unsigned r4, unsigned r5, unsigned r6, unsigned r7) { unsigned dtb_passed = 0; - char cmdline_passed[COMMAND_LINE_SIZE] = { 0, }; + char cmdline_passed[COMMAND_LINE_SIZE] __maybe_unused = { 0, }; #if defined(CONFIG_NIOS2_PASS_CMDLINE) if (r4 == 0x534f494e) { /* r4 is magic NIOS */ -- 2.1.4
