The patch modifies the horizontal front porch (HFP) timing to correct a refresh rate discrepancy that was causing stylus malfunction. **Summary Assessment:** - **Purpose**: Clear and well-defined - fixes refresh rate from 120.4Hz to 120Hz for stylus compatibility - **Scope**: Minimal and focused - only touches the affected timing parameters - **Correctness**: The math appears sound, but there are some review concerns - **Testing**: Implied hardware testing (measured refresh rate), but not explicitly documented **Key Concerns:** 1. Lack of detailed justification for the specific HFP value chosen 2. No explanation of why this timing change is safe/correct per panel datasheet 3. Missing information about testing methodology and devices tested 4. Potential impact on other display characteristics not addressed --- --- Generated by Claude Code Patch Reviewer
