This is a single-patch submission for stable kernel backport (AUTOSEL 6.18-5.10) that removes unused variables from the Tegra DRM driver. The patch addresses a GCC 16 build failure caused by the `-Werror=unused-but-set-variable` flag being enabled by default.

**Summary Assessment:**
- **Type:** Build fix
- **Scope:** Minimal - removes dead code only
- **Risk:** Very low - no functional changes
- **Correctness:** The fix is correct but reveals a potential code smell

**Key Concerns:**
1. The variable `j` was being incremented by 8 in a loop that processes 7 bytes at a time, suggesting possible original intent for tracking bit positions
2. The commit message and "LLM Generated explanations" section is unusual for kernel patches
3. This appears to be an AUTOSEL (automatically selected) stable backport

**Recommendation:** The patch is technically correct as a build fix, but warrants investigation into whether the original code was buggy or incomplete.
