Claude review: drm/xe: Don't emit UTS_RELEASE as part of device coredump

Patch Review

**Correctness:** The patch is mechanically correct. It removes one `drm_puts` call and the surrounding code compiles fine without it.

**Concern — Loss of diagnostic information:**

```c
-	drm_puts(&p, "kernel: " UTS_RELEASE "\n");
```

This line provides the kernel version in coredumps. When users submit bug reports with coredump data attached, the kernel version is one of the first things developers check. Removing it means developers will need to ask users for this information separately or rely on other metadata (e.g., dmesg, uname output) that may not always be included in the report.

**Concern — Inconsistency with other drivers:**

The author's own grep shows that amdgpu, msm, and xe all emit `UTS_RELEASE` in their coredumps. Removing it from xe alone creates an inconsistency. If this change is desirable, it should be a series covering all DRM drivers that use this pattern.

**Concern — Weak justification:**

The commit message says *"It's little helpful to emit the kernel version in the device coredump"* but doesn't provide evidence for this claim. The author even hedges in the cover letter. Build reproducibility is a valid concern but is a niche developer workflow issue, not a reason to remove diagnostic data from production coredumps.

**Alternative approach:** If the goal is to avoid compile-time `UTS_RELEASE` dependencies, the line could be changed to use the runtime equivalent:

```c
drm_printf(&p, "kernel: %s\n", utsname()->release);
```

This would emit the same information at dump time without causing `xe_devcoredump.o` to be rebuilt when `UTS_RELEASE` changes. This addresses the build reproducibility concern while preserving the diagnostic value.
