Claude review: drm/i915/guc: fix corrupted copyright symbols in selftest files

[Claude Code Review Bot <claude-review@example.com>]

Patch Review

**Summary**: Replaces corrupted UTF-8 sequences with proper © symbols in copyright headers of two GuC selftest files.

**Commit Message Analysis**:
- Subject line is clear and follows kernel conventions (subsystem prefix: drm/i915/guc)
- Body adequately describes what is changed
- Missing: How this corruption occurred, whether it's widespread

**Technical Review**:

**Analysis**:
- Change is purely cosmetic in a comment block
- Maintains proper SPDX license identifier (untouched)
- File encoding issue correction - no functional impact
- The replacement character sequence suggests double corruption or encoding detection failure

**Analysis**:
- Identical fix pattern to first file
- Different copyright year (2019 vs 2021) - both appear legitimate based on file history

**Issues Found**: None - patch is correct as-is

**Questions for Maintainer**:
1. Should we audit the entire i915 driver tree for similar corruption?
2. Is there a preference for "©" vs "(C)" in i915 copyright headers?
3. Do the build/CI systems validate UTF-8 encoding in source files?

**Tested-by / Reviewed-by**: None present - this is expected for initial submission

**Recommendation**: 

**Acked-by** - This patch is appropriate and correctly fixes the stated issue.

**Suggestions**:
- Consider running: `git grep -P '[^\x00-\x7F].*Copyright.*Intel' drivers/gpu/drm/i915/` to find other potential encoding issues
- If widespread, might justify a larger cleanup series
- For v2 (if needed): Add note about whether this was checked tree-wide
