[PATCH 39/46] drm/amd/display: use even ODM slice width for two pixels per container

[Wayne Lin <Wayne.Lin@amd.com>]

From: Wenjing Liu <wenjing.liu@amd.com>

[why]
When optc uses two pixel per container, each ODM slice width must be an
even number.

[how]
If ODM slice width is odd number increase it by 1.
