Static analysis reports this problem
amdgpu_ras.c:2324:2: warning: 2nd function call argument is an
uninitialized value
atomic_set(&con->ras_ce_count, ce_count);
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
ce_count is normally set by the earlier call to
amdgpu_ras_query_error_count(). But amdgpu_ras_query_error_count()
can return early without setting, leaving its error count parameters
in a garbage state.
Initialize the error count parameters earlier.
Fixes: a46751fbcde5 ("drm/amdgpu: Fix RAS function interface")
