SiI9234 transmitter converts eTMDS/HDMI signal to MHL 1.0.
It is controlled via I2C bus. Its interaction with other
devices in video pipeline is performed mainly on HW level.
The only interaction it does on device driver level is
filtering-out unsupported video modes, it exposes drm_bridge
interface to perform this operation.

Commit 669c9215 ("drm/atomic: Make async plane update checks work as
intended, v2.") assumed incorrectly that if only 1 plane is matched in
the loop, the variables will be set to that plane. In reality we reset
them to NULL every time a new plane was iterated. This behavior is
surprising, so fix this by making the for loops only assign the
variables on a match.

When we have not added all the planes/crtc/connector to the state, and
there's a few NULL ones after the last one we iterated, te assumption
is broken that the pointers will hold the values from the last loop
iteration, which holds true for all other for_each macros we're using.
Except of course the iterator pointer itself, but that one really is
entirely internal.

fbdev is in maintenance only, except that it's still used by drm
through the drm fbdev emulation, to be able to use fbcon. And people
might want to sometimes extend fbcon to enable new features for drm
drivers, e.g. Hans' panel orientation work.

The problem is that when those patches only touch fbdev code they'll
never show up on drm developer's radar, which means we end up with
designs that don't really fit whell into the full stack. That happened
a bit with the panel orientation work, where an fbcon patch made it
into 4.14, implementing a design that won't really work on the drm
side. Which means we now have to redo things, and on top coordinate 2
subsystem trees.

Since fbdev is super low-volume we can prevent this in the future by
simply adding the dri-devel mailing list to the fbdev subsystem.

Pull timer fixes from Thomas Gleixner:
 "This adds a new timer wheel function which is required for the
  conversion of the timer callback function from the 'unsigned long
  data' argument to 'struct timer_list *timer'. This conversion has two
  benefits:

   1) It makes struct timer_list smaller

   2) Many callers hand in a pointer to the timer or to the structure
      containing the timer, which happens via type casting both at setup
      and in the callback. This change gets rid of the typecasts.

  Once the conversion is complete, which is planned for 4.15, the old
  setup function and the intermediate typecast in the new setup function
  go away along with the data field in struct timer_list.

  Merging this now into mainline allows a smooth queueing of the actual
  conversion in the affected maintainer trees without creating
  dependencies"
