Leon Romanovsky f5029e752b Ib/usnic: Explicitly include usnic headers
Sparse tool complains about undeclared symbols in usnic_ib_verbs.c
and usnic_ib_sysfs.c This is caused by lack of direct include of
appropriate usnic_ib_verbs.h and usnic_ib_sysfs.h, where all
these functions were declared.

Simple include eliminates 30 warnings similar to the below one:

drivers/infiniband/hw/usnic/usnic_ib_sysfs.c:304:6: warning: symbol
				'usnic_ib_sysfs_unregister_usdev' was
				not declared. Should it be static?

Peter Zijlstra 2c935bc572 locking/atomic, kref: Add kref_read()
Since we need to change the implementation, stop exposing internals.

Provide kref_read() to read the current reference count; typically
used for debug messages.

Kills two anti-patterns:

	atomic_read(&kref->refcount)
	kref->refcount.counter

Jeff Squyres 3805eade3b usnic: add missing clauses to BSD license
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.
