This is a single-patch series addressing a memory leak bug in the Samsung DSIM bridge driver. The patch fixes a legitimate resource leak where `drm_bridge_add()` is called early in `samsung_dsim_host_attach()`, but subsequent error paths fail to call the corresponding `drm_bridge_remove()`. The fix implements proper error unwinding using goto labels, following standard kernel patterns.

**Strengths:**
- Correctly identifies and fixes a real resource leak
- Uses standard kernel error handling patterns (goto labels)
- Includes appropriate Fixes tag and Cc: stable
- Handles both bridge removal and TE IRQ cleanup in error paths
- Code movement is minimal and justified (avoids forward declaration)

**Areas for improvement:**
- Patch versioning format (should use `[PATCH v2]` in subject)
- The changelog placement (v2 notes should go after the `---` separator)

**Overall assessment:** This is a solid bug fix that should be merged. The technical approach is correct, and the code follows kernel conventions. The only issues are minor formatting/process improvements that were already pointed out by the reviewer.
