Subject: [PATCH] drm/amd/display: remove redundant initialization of variable result

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

The variable result is being initialized with a value that is
never read and it is being updated later with a new value.  The
initialization is redundant and can be removed.

Addresses-Coverity: ("Unused value")
