When RPC_DEBUG is unset, the dprintk() macro does nothing, causing the 'buf' variable in svc_printk to become unused. Marking it as __maybe_unused avoids a harmless gcc warning.
Without this patch, building at91_dt_defconfig results in: net/sunrpc/svc.c: In function 'svc_printk': net/sunrpc/svc.c:1051:7: warning: unused variable 'buf' [-Wunused-variable] Signed-off-by: Arnd Bergmann <[email protected]> Cc: "J.
