Staging driver fixes for 3.14-rc3 

Here are a number (lots, I know) of fixes for staging drivers to resolve
 a bunch of reported issues.
 
 The largest patches here is one revert of a patch that is in 3.14-rc1 to
 fix reported problems, and a sync of a usb host driver that required
 some ARM patches to go in before it could be accepted (which is why it
 missed -rc1).
 
 All of these have been in linux-next for a while with no reported issues.
