Subject: [PATCH 5.0 093/115] s390/mem_detect: Use IS_ENABLED(CONFIG_BLK_DEV_INITRD)

From: Joe Perches <joe@...ches.com>

commit 2d4ea4b95cae3133de6b18ec5d5a42ee824fa0ef upstream.

IS_ENABLED should generally use CONFIG_ prefaced symbols and
it doesn't appear as if there is a BLK_DEV_INITRD define.
