When the aic7xxx driver is compiled in, you get the following warnings: drivers/scsi/aic7xxx/aic7xxx_osm.c:439: warning: `aic7xxx' defined but not used drivers/scsi/aic7xxx/aic7xxx_osm.c:445: warning: `dummy_buffer' defined but not used I don't think you need aic7xxx or dummy_buffer unless it's a module, so the attached patch #ifdef's the declarations as well. Compile tested on ppc64.
