From e05ee4e986d173791e83f4370a120bd8ff691b7d Mon Sep 17 00:00:00 2001 From: Shivasharan S Date: Fri, 5 Jan 2018 05:27:36 -0800 Subject: [PATCH] scsi: megaraid_sas: zero out IOC INIT and stream detection memory 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. Signed-off-by: Sumit Saxena Signed-off-by: Shivasharan S Signed-off-by: Martin K.
