kzalloc doesn't return ERR_PTR, so there is no need to test for it.
The semantic match that finds this problem is as follows:
(http://coccinelle.lip6.fr/)
// <smpl>
@@
expression x,e;
@@
* x = kzalloc(...)
... when != x = e
* IS_ERR_OR_NULL(x)
// </smpl>

They were already implemented at a lower layer, but the upper level
routine placed arbitrary restrictions on which transitions were
permitted. Simplify the state machine logic to live wholly in
usnic_ib_qp_grp_modify.

The usnic_verbs kernel module was clearly marked with the following in
its code:
MODULE_LICENSE("Dual BSD/GPL");
However, we accidentally left a few clauses of the BSD text out of the
license header in all the source files. This commit fixes that: all
the files are properly dual BSD/GPL-licensed. Contributors that might
have been confused by this have been contacted to get their permission
and are Cc:ed here.

Vendors should be able to pass vendor specific data to/from
user-space via query_device uverb. In order to do this,
we need to pass the vendors' specific udata.

Add a new ib_cq_init_attr structure which contains the
previous cqe (minimum number of CQ entries) and comp_vector
(completion vector) in addition to a new flags field.
All vendors' create_cq callbacks are changed in order
to work with the new API.
This commit does not change any functionality.
