The function usnic_ib_qp_grp_get_chunk only returns an ERR_PTR value or a
valid pointer, never NULL. The same is true of get_qp_res_chunk, which
just returns the result of calling usnic_ib_qp_grp_get_chunk. Simplify
IS_ERR_OR_NULL to IS_ERR in both cases.
The semantic patch that makes this change is as follows:
(http://coccinelle.lip6.fr/)
// <smpl>
@@
expression t,e;
@@
t = \(usnic_ib_qp_grp_get_chunk(...)\|get_qp_res_chunk(...)\)
... when != t=e
- IS_ERR_OR_NULL(t)
+ IS_ERR(t)
@@
expression t,e,e1;

Since kzalloc returns memory address, not error code,
it should be checked whether it is null or not.

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.

usNIC calls WARN_ON(spin_is_locked..) at few places. In some of these
instances, the call is made while holding a spinlock. Change
all WARN_ON(spin_is_locked...) calls in usNIC to
lockdep_assert_held to make it fool-proof bc the latter can be
called while holding a spinlock and unlike spin_is_locked,
lockdep_assert_held also works correctly on UP.
