Subject: [PATCH] scsi: aacraid: report -ENOMEM to upper layer from
aac_convert_sgraw2()
References: bsc#1049519,FATE#322889
Git-commit: 96676246981b8321fb7bcaf51147f3be7c436af5
Patch-Mainline: v4.14-rc1
aac_convert_sgraw2() kmalloc memory and return -1 on error, which should
be -ENOMEM. However, nobody is checking return value, so with this
change, -ENOMEM is propagated to upper layer.
