Subject: [PATCH] scsi: megaraid_sas: zero out IOC INIT and stream detection
memory
References: bsc#1077408
Git-commit: e05ee4e986d173791e83f4370a120bd8ff691b7d
Patch-mainline: v4.16-rc1
Memory allocated for IOC_INIT command and stream detection array are not
zero'd before using. Use kzalloc instead of kmalloc to zero out the
memory allocated.
