In 2.6.24-rc1 I see the following warning:
drivers/scsi/sym53c8xx_2/sym_glue.c: In function "sym_eh_handler":
drivers/scsi/sym53c8xx_2/sym_glue.c:612: warning: "io_reset" may be used
uninitialized in this function
Although gcc is wrong and the code is actually correct, it can easily
be made more obvious to keep the compiler quiet.
