[PATCH] drm/amd/pm: initialize variable

From: trix
Date: Fri Apr 30 2021 - 14:05:18 EST


From: Tom Rix <trix@xxxxxxxxxx>

Static analysis reports this problem

amdgpu_pm.c:478:16: warning: The right operand of '<' is a garbage value
for (i = 0; i < data.nums; i++) {
^ ~~~~~~~~~

In some cases data is not set. Initialize to 0 and flag not setting
data as an error with the existing check.
