Subject: [PATCH][next] 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, it is being updated immediately afterwards in both branches
of an if statement. The assignment is redundant and can be removed.

Addresses-Coverity: ("Unused value")
