From: Colin Ian King <colin.king@xxxxxxxxxxxxx>
Currently result is not initialized, so it contains a garbage value and
this is or'd with data from vega10_program_didt_config_registers() which
can end up with a non-zero value when the result should be zero. Fix
this by ensuring result is initialized to zero.
Detected by CoverityScan, CID#1466088 ("Uninitialized scalar variable")
Fixes: 9b7b8154cdb8 ("drm/amd/powerplay: added didt support for vega10")
