We get 2 warnings when building kernel with W=1: drivers/scsi/pm8001/pm80xx_hwi.c:69:6: warning: no previous prototype for 'pm80xx_pci_mem_copy' [-Wmissing-prototypes] drivers/scsi/pm8001/pm80xx_hwi.c:4540:6: warning: no previous prototype for 'mpi_set_phy_profile_req' [-Wmissing-prototypes]
In fact, these functions are only used in the file in which they are declared and don't need a declaration, but can be made static. so this patch marks these functions with 'static'.
