[PATCH] scsi: target: return -ENOMEM when kzalloc failed

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]


The driver is using -1 instead of the -ENOMEM defined macro to specify
that a buffer allocation failed.

drivers/target/iscsi/iscsi_target.c:691 iscsi_target_init_module() warn: returning -1 instead of -ENOMEM is sloppy.
