[PATCH] drm/amd/pm: initialize variable

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
