From: Prasad J Pandit Date: Wed, 25 May 2016 17:41:44 +0530 Subject: [PATCH] scsi: megasas: initialise local configuration data buffer When reading MegaRAID SAS controller configuration via MegaRAID Firmware Interface(MFI) commands, routine megasas_dcmd_cfg_read uses an uninitialised local data buffer. Initialise this buffer to avoid stack information leakage.
