Claude review: drm/amdgpu/userq: convert comma to semicolon

Patch Review

**Assessment: Low-priority cleanup, technically correct**

The two changed lines (lines 964 and 971 of the original file) both have the pattern:

```c
ptr = u64_to_user_ptr(wait_info->bo_read_handles),
```

changed to:

```c
ptr = u64_to_user_ptr(wait_info->bo_read_handles);
```

The trailing `,` makes the assignment part of a comma expression, but since the next statement is on a separate line and the comma's result (the value of `ptr`) is discarded, there is no behavioral difference. The fix is correct — semicolons are the intended statement terminators here, and the commas were likely typos (possibly from copy-paste of an initializer list or similar).

**Minor observations:**
- The commit message is fine and accurately describes the change as having no functional impact.
- "Compile tested only" is acceptable for this type of change, though runtime testing would always be preferred for driver code.
- The "Found by inspection" note is honest but also a hallmark of low-value automated/mechanical cleanup patches. Maintainers may or may not care to take these.

**Verdict:** Correct but trivial. No objections to merging, but also no urgency.
