[PATCH 1/2] drm/amd/display: Return directly after a failed kzalloc() in dc_create()

[Markus Elfring]

From: Markus Elfring <elfring at users.sourceforge.net>
Date: Sat, 19 Dec 2020 18:04:33 +0100

* Return directly after a call of the function “kzalloc” failed
  at the beginning.

* Delete a label which became unnecessary with this refactoring.
