[PATCH 3/5] drm/amd/display: Delete three unnecessary variable initialisations in trigger_hotplug()

[Markus Elfring]

Date: Tue, 11 Apr 2023 12:34:42 +0200

The variables “link”, “wr_buf” and “ret” will eventually be set
to appropriate values a bit later.
Thus omit the explicit initialisation at the beginning.
