Subject: [PATCH] [SCSI] mvsas: mark symbols static where possible
We get a few warnings when building kernel with W=1:
drivers/scsi/mvsas/mv_sas.c:77:18: warning: no previous prototype for 'mvs_find_dev_mvi' [-Wmissing-prototypes]
drivers/scsi/mvsas/mv_sas.c:105:5: warning: no previous prototype for 'mvs_find_dev_phyno' [-Wmissing-prototypes]

drivers/scsi/mvsas/mv_sas.c:1188:5: warning: no previous prototype for 'mvs_dev_found_notify' [-Wmissing-prototypes]

drivers/scsi/mvsas/mv_sas.c:1614:6: warning: no previous prototype for 'mvs_set_sense' [-Wmissing-prototypes]
drivers/scsi/mvsas/mv_sas.c:1653:6: warning: no previous prototype for 'mvs_fill_ssp_resp_iu' [-Wmissing-prototypes]
drivers/scsi/mvsas/mv_64xx.c:139:6: warning: no previous prototype for 'mvs_64xx_clear_srs_irq' [-Wmissing-prototypes]
drivers/scsi/mvsas/mv_64xx.c:566:6: warning: no previous prototype for 'mvs_64xx_make_prd' [-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'.
