Subject: serial: omap: suspend device on probe errors

From: Johan Hovold <[email protected]>

commit 77e6fe7fd2b7cba0bf2f2dc8cde51d7b9a35bf74 upstream.

Make sure to actually suspend the device before returning after a failed (or deferred) probe.

Note that autosuspend must be disabled before runtime pm is disabled in order to balance the usage count due to a negative autosuspend delay as well as to make the final put suspend the device synchronously.
