It looks like there's been a bug in the module parameter setup forever.
The upshot doesn't really matter, because even if no parameters are ever
set, we just call sym53c416_setup() three times, but the zero values in
the arrays eventually cause nothing to happen. Unfortunately gcc has
started to notice this now too:
drivers/scsi/sym53c416.c: In function 'sym53c416_detect':
drivers/scsi/sym53c416.c:624: warning: the address of 'sym53c416' will always evaluate as 'true'
drivers/scsi/sym53c416.c:630: warning: the address of 'sym53c416_1' will always evaluate as 'true'
drivers/scsi/sym53c416.c:636: warning: the address of 'sym53c416_2' will always evaluate as 'true'
drivers/scsi/sym53c416.c:642: warning: the address of 'sym53c416_3' will always evaluate as 'true'
So fix this longstanding bug to keep gcc quiet.
