Subject: Claude review: drm/rockchip: vop2: Drop redundant zero-init in setup_layer_mixer()
Date: Tue, 05 May 2026 08:08:46 +1000 [thread overview]
Message-ID: <review-patch4-20260504-vop2-layer-cfg-tmout-v1-4-730226a7331e@collabora.com> (raw)
In-Reply-To: <20260504-vop2-layer-cfg-tmout-v1-4-730226a7331e@collabora.com>
Patch Review
**Verdict: Trivially correct.**
```diff
- u32 layer_sel = 0;
+ u32 layer_sel;
...
- u32 atv_layer_sel = 0;
+ u32 atv_layer_sel;
```
Both variables are unconditionally assigned before use (`layer_sel = vop2->old_layer_sel` and `atv_layer_sel = vop2_readl(...)`) after patch 3. The zero-init is indeed dead.
No issues.
