Subject: Claude review: drm/panel: focaltech-ota7290b: Fix error check for devm_drm_panel_alloc()
Date: Tue, 05 May 2026 11:48:20 +1000 [thread overview]
Message-ID: <review-patch1-20260429080527.1456732-1-nichen@iscas.ac.cn> (raw)
In-Reply-To: <20260429080527.1456732-1-nichen@iscas.ac.cn>
Patch Review
**Status: Correct**
The change:
```c
- if (!ctx)
- return -ENOMEM;
+ if (IS_ERR(ctx))
+ return PTR_ERR(ctx);
```
This is the standard error-handling pattern for functions returning `ERR_PTR`. 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.**
