This is a single-patch series that addresses a cosmetic issue in copyright headers. The patch fixes corrupted UTF-8 copyright symbols (©) that were rendered as Unicode replacement characters in two i915 GuC selftest files.

**Scope**: Documentation/cosmetic fix only - no functional changes
**Risk Level**: Minimal - only modifies copyright header comments
**Testing Required**: None (comment-only changes)

The patch is straightforward and appropriate. However, there are some considerations:

1. **Completeness**: The patch only fixes 2 files. A broader audit may be warranted to check if other files in the i915 driver (or kernel-wide) have the same corruption.

2. **Root Cause**: The commit message doesn't explain how these became corrupted or whether this is a systematic issue that could recur.

3. **Alternative Approach**: Some kernel subsystems prefer ASCII-only copyright headers using "(C)" instead of "©" to avoid encoding issues entirely. This might be worth discussing with maintainers.

**Recommendation**: The patch itself is fine and can be merged, but consider:
- Checking for similar issues in other i915 files
- Documenting whether UTF-8 copyright symbols are preferred over ASCII equivalents in i915
