Small driver suspend() fixes in preparation for the PRETHAW events: - Only compare message events for equality against PM_EVENT_* codes; not against integers, or using greater/less-than comparisons. (PM_EVENT_* should really become a __bitwise thing.) - Explicitly test for SUSPEND events (rather than not-something-else) before suspending devices. - Removes more of the confusion between a pm_message_t (wraps event code) and a "state" ... suspend() originally took a target system state. These updates are correct and appropriate even without new PM_EVENT codes. benh: "I think in the Mesh case, we should handle the freeze case as well or we might get wild DMA."
