Problem in BSW/BYT runtime PM, reported at:

[ INFO: possible circular locking dependency detected ]
4.5.0-gfxbench+ #1 Not tainted
gem_exec_basic/5896 is trying to acquire lock:
 (&dev->struct_mutex){+.+.+.}, at: [<ffffffff81514ea1>]
but task is already holding lock:
 (&mm->mmap_sem){++++++}, at: [<ffffffff8117d8c4>]

which lock already depends on the new lock."

Lockdep issue (completely unrelated to renaming functions :P), this
whole chain causing multiple splats is being worked on. Opened a bug to
track this specific warn:
