scsi: raid_attrs: fix unused variable warning
I ran into a new warning on randconfig kernels: drivers/scsi/raid_class.c: In function 'raid_match': drivers/scsi/raid_class.c:64:24: error: unused variable 'i' [-Werror=unused-variable] This looks like a very old problem that for some reason was very hard to run into, but it is very easy to fix, by replacing the incorrect #ifdef with a simpler IS_ENABLED() check. Fixes: fac829fdcaf4 ("[SCSI] raid_attrs: fix dependency problems") Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Martin K. Petersen <martin.petersen@oracle.com>
