2026-01-05drm/amdgpu: Use explicit VCN instance 0 in SR-IOV initSrinivasan Shanmugam
vcn_v2_0_start_sriov() declares a local variable "i" initialized to zero and uses it only as the instance index in SOC15_REG_OFFSET(UVD, i, ...). The value is never changed and all other fields are taken from adev->vcn.inst[0], so this path only ever programs VCN instance 0. This triggered a Smatch: warn: iterator 'i' not incremented Replace the dummy iterator with an explicit instance index of 0 in SOC15_REG_OFFSET() calls.

2026-01-05drm/amdkfd: Fix signal_eviction_fence() bool return valueSrinivasan Shanmugam
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.
