Subject: [PATCH][next] drm/amdkfd: remove redundant initialization to variable r

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

The variable r 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")
