Subject[PATCH 4.18 160/197] drm/amd/powerplay: fixed uninitialized value
Date
4.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Evan Quan <evan.quan@amd.com>

commit 1ce0688f3f6a9e9d34ae66bf779d54855def7bec upstream.

The 'result' is not initialized correctly. It causes the API
return an error code even on success.
