[PATCH for-3.17 2/5] ib/mad: update module to [pr|dev]_* style print messages

ira.weiny-ral2JQCrhuEAvxtiuMwx3w
2014-08-08T23:00:53Z

Use dev_* style print when struct device is available.

Also combine previously line broken user-visible strings as per
Documentation/CodingStyle

"However, never break user-visible strings such as printk messages, because
that breaks the ability to grep for them."
