scsi: acornscsi: mark calc_sync_xfer as __maybe_unused
The calc_sync_xfer function is only used if CONFIG_SCSI_ACORNSCSI_SYNC is set, otherwise we get a compiler warning: scsi/arm/acornscsi.c:680:15: warning: 'calc_sync_xfer' defined but not used [-Wunused-function] unsigned char calc_sync_xfer(unsigned int period, unsigned int offset) This marks the function as __maybe_unused to shut up the warning and silently drop the function in the object code when there is no caller.
