The header documentation at `drm_panel.h:316` explicitly states: > Returns: Pointer to container structure embedding the panel, ERR_PTR on failure. The Fixes tag references `07853e954248 ("drm/panel: add driver for Waveshare 8.8" DSI TOUCH-A panel")` which is the commit that introduced the driver with this bug. **Minor observations:** - The commit message is clear and accurate. - The Fixes tag is appropriate since this is a real bug in the original driver commit. - No other issues with the surrounding code visible in the diff context. **No changes requested.** --- Generated by Claude Code Patch Reviewer
