2026-01-05drm/amdkfd: Fix signal_eviction_fence() bool return valueSrinivasan Shanmugam-1/+1
signal_eviction_fence() is declared to return bool, but returns -EINVAL when no eviction fence is present. This makes the "no fence" or "the NULL-fence" path evaluate to true and triggers a Smatch warning. v2: Return true instead to explicitly indicate that there is no eviction fence to signal and that eviction is already complete. This matches the existing caller logic where a NULL fence means "nothing to do" and allows restore handling to proceed normally.
