Subject[PATCH 4.14 060/115] scsi: raid_attrs: fix unused variable warning
Date
[ Upstream commit 0eeec01488da9b1403c8c29e73eacac8af9e4bf2 ]

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")
