Subject: [PATCH] scsi: megaraid: silence a static checker bug
Git-commit: 27e833dabab74ee665e487e291c9afc6d71effba
Patch-mainline: v4.18-rc1
References: bsc#1118139
If we had more than 32 megaraid cards then it would cause memory
corruption. That's not likely, of course, but it's handy to enforce it
and make the static checker happy.
