[PATCH] iscsi-target: return -ENOMEM instead of -1 in case of failed kmalloc()

From: Luis de Bethencourt
Date: Mon Oct 19 2015 - 16:18:36 EST


Smatch complains about returning hard coded error codes, silence this
warning.

drivers/target/iscsi/iscsi_target_parameters.c:211 iscsi_create_default_params() warn: returning -1 instead of -ENOMEM is sloppy

Hi,

This doesn't change the functionality. It is just about using the more specific
errno. And at the same time silencing smatch.

Thanks,
Luis
