drm/msm: Fix NULL deref on bind/probe deferral

This patch avoids dereferencing msm_host->dev when it is NULL.

If we find ourselves tearing down dsi before calling

pointer is NULL and trying to extract priv from it will fail.

function has been a stub for ~5 years). Correctness FTW! \o/

drm/msm/mdp5: Use the new private_obj state

This replaces the usage of the subclassed atomic state (mdp5_state)
with a private_obj state embedded within drm_atomic_state. The latter
method is the preferred approach, since it's simpler to implement
and less prone to errors.

The new API replaces the older and equivalent mdp5_state usage in the
following pattern:
- References to "mdp5_kms->state" (i.e, the old/existing state) is
  replaced with mdp5_get_existing_global_state(). In the atomic_check
  path, this should be called with the glob_state_lock drm_modeset_lock
  alredy taken.
- References to "mdp5_get_state()" are replaced with
  mdp5_get_global_state(). This acquires glob_state_lock and uses
  drm_atomic_get_private_obj_state() to create a new duplicated state.

Changes in v3:
- Acquire glob_state_lock in mdp5_smp.c
- Added to the msm atomic helper patch set

drm/msm/mdp5: Add global state as a private atomic object

Global shared resources (hwpipes, hwmixers and SMP) for MDP5 are
implemented as a part of atomic state by subclassing drm_atomic_state.

The preferred approach is to use the drm_private_obj infrastructure
available in the atomic core.

mdp5_global_state is introduced as a drm atomic private object. The two
funcs mdp5_get_global_state() and mdp5_get_existing_global_state() are
the two variants that will be used to access mdp5_global_state.

This will replace the existing mdp5_state struct (which subclasses
drm_atomic_state) and the funcs around it. These will be removed later
once we mdp5_global_state is put to use everywhere.

Changes in v3:
- Added glob_state_lock instead of pushing it into the core
- Added to the msm atomic helper patch set

drm/msm: Fix possible null dereference on failure of get_pages()

Commit 62e3a3e342af changed get_pages() to initialise
msm_gem_object::pages before trying to initialise msm_gem_object::sgt,
so that put_pages() would properly clean up pages in the failure
case.

However, this means that put_pages() now needs to check that
msm_gem_object::sgt is not null before trying to clean it up, and
this check was only applied to part of the cleanup code.  Move
it all into the conditional block.  (Strictly speaking we don't

Revert "drm/i915/edp: Allow alternate fixed mode for eDP if available."

This reverts commit dc911f5bd8aacfcf8aabd5c26c88e04c837a938e.

Per the report, no matter what display mode you select with xrandr, the
i915 driver will always select the alternate fixed mode. For the
reporter this means that the display will always run at 40Hz which is
quite annoying. This may be due to the mode comparison.

But there are some other potential issues. The choice of alt_fixed_mode
seems dubious. It's the first non-preferred mode, but there are no
guarantees that the only difference would be refresh rate. Similarly,
there may be more than one preferred mode in the probed modes list, and
the commit changes the preferred mode selection to choose the last one
on the list instead of the first.

(Note that the probed modes list is the raw, unfiltered, unsorted list
of modes from drm_add_edid_modes(), not the pretty result after a
drm_helper_probe_single_connector_modes() call.)

Finally, we already have eerily similar code in place to find the
downclock mode for DRRS that seems like could be reused here.

Back to the drawing board.

Note: This is a hand-crafted revert due to conflicts. If it fails to
backport, please just try reverting the original commit directly.

drm/amd/display: Clear underflow status for debug purposes

We want to keep underflow sticky bit on for the longevity tests outside
of test environment. For debug purposes it is, however, useful to clear
underflow status after the test that caused it so that the following
tests are not affected. This change fullfils both requirements by clearing
the underflow only from within Windows or Diags test environment.
