From 27e833dabab74ee665e487e291c9afc6d71effba Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Thu, 3 May 2018 13:54:32 +0300 Subject: [PATCH] scsi: megaraid: silence a static checker bug 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. Signed-off-by: Dan Carpenter Signed-off-by: Martin K.
