[PATCH 01/13] drm/amd/display: Fix for variable may be used uninitialized error

[Jasdeep Dhillon]

From: Eric Bernstein <eric.bernstein@amd.com>

[Why]
Build failure due to ‘status’ may be used uninitialized

[How]
Initialize status to LINK_TRAINING_SUCCESS

[PATCH 02/13] drm/amd/display: Fix stream->link_enc unassigned during stream removal

[Jasdeep Dhillon]

From: Nicholas Kazlauskas <nicholas.kazlauskas@amd.com>

[Why]
Found when running igt@kms_atomic.

Userspace attempts to do a TEST_COMMIT when 0 streams which calls
dc_remove_stream_from_ctx. This in turn calls link_enc_unassign
which ends up modifying stream->link = NULL directly, causing the
global link_enc to be removed preventing further link activity
and future link validation from passing.

[How]
We take care of link_enc unassignment at the start of
link_enc_cfg_link_encs_assign so this call is no longer necessary.

Fixes global state from being modified while unlocked.

[PATCH 03/13] drm/amd/display: limit unbounded requesting to 5k

[Jasdeep Dhillon]

From: Dmytro Laktyushkin <Dmytro.Laktyushkin@amd.com>

Unbounded requesting is unsupported on pipe split modes
and this change prevents us running into such a situation
with wide modes.
