Subject: [PATCH][next] drm/amd/display: remove redundant assignment to status

From: Colin Ian King <colin.king@...onical.com>

The variable status is initialized with a value that is never read
and status is reassigned several statements later. This initialization
is redundant and can be removed.

Addresses-Coverity: ("Unused value")
