Issues

• Integration presence: Both commits are missing from qcom-next and topics branches. This is expected for new vendor-specific work but should be tracked for integration.

Verdict

Vendor-only commits with correct QCLINUX: prefix. No upstream validation required. Commits are well-formed and appropriately scoped for vendor tree. Missing from qcom-next/topics is expected for new work pending integration.

Final Summary

1. Lore link present: No — QCLINUX: prefix; no lore link expected or required
2. Lore link matches PR commits: N/A — no lore link to compare against
3. Upstream patch status: N/A — vendor-only change, not posted upstream
4. PR present in qcom-next/topics: Fail - 2/2 commit(s) are missing from both qcom-next and topics (expected for new vendor work)

❌ checkpatch

Root cause: Multiple coding style violations including trailing whitespace, spaces instead of tabs, undocumented DT compatible strings, and lines exceeding 100 columns.

Commit da3c917 ("QCLINUX: arm64: dts: qcom: enable SDE DSI on rb3gen2"):

WARNING: DT compatible string "qcom,dsi-ctrl-hw-v2.5" appears un-documented
  #24: FILE: arch/arm64/boot/dts/qcom/kodiak-sde.dtsi:269

WARNING: DT compatible string "qcom,dsi-phy-v4.1" appears un-documented

  #114: FILE: arch/arm64/boot/dts/qcom/kodiak-sde.dtsi:485

total: 0 errors, 3 warnings, 0 checks, 207 lines checked

Fix:

1. Trailing whitespace and indentation errors (commit 1):

   # Remove trailing whitespace
   sed -i 's/[[:space:]]*$//' arch/arm64/boot/dts/qcom/kodiak-sde.dtsi
   
   # Fix spaces to tabs (lines 320, 404-436)
   # Manually review and convert leading spaces to tabs in these sections

2. Long lines (commit 1):
   Wrap lines 187 and 190 in kodiak-sde.dtsi to stay within 100 columns.

3. Multiple blank lines (commit 1):
   Remove extra blank line at line 32 in kodiak-sde.dtsi.

4. Undocumented DT compatible strings (both commits):
   These are vendor-specific Qualcomm display driver compatible strings. Options:

   • Add binding documentation in Documentation/devicetree/bindings/display/msm/ (preferred for upstream)
   • Accept as vendor-specific for internal tree (checkpatch will still warn)

Reproduce locally:

./scripts/checkpatch.pl --strict --ignore FILE_PATH_CHANGES --git 7a0df21b1d7d..8c023ecb8174

❌ check-patch-compliance

Root cause: Both commits use QCLINUX: prefix, which is not in the allowed list for check-patch-compliance.

Failure details:

Checking commit: QCLINUX: arm64: dts: qcom: Add rb3gen2 SDE overlay dts
Commit summary does not start with a required prefix

Checking commit: QCLINUX: arm64: dts: qcom: enable SDE DSI on rb3gen2
Commit summary does not start with a required prefix

Fix:

The check-patch-compliance checker only accepts these prefixes: FROMLIST:, FROMGIT:, UPSTREAM:, BACKPORT:.

Since these are vendor-specific DTS overlay additions with no upstream equivalent, you have two options:

1. If posted to a mailing list: Change prefix to FROMLIST: and add Link: trailer pointing to the lore.kernel.org URL.

2. If vendor-only (not posted upstream): The QCLINUX: prefix is correct for vendor-only changes, but check-patch-compliance will always fail. This is a known limitation of the checker for vendor-internal commits.

Note: For the tech/overlay/dt branch, vendor-only overlay DTS files are common and QCLINUX: is the appropriate prefix. The checker failure is expected for this type of change.

---

❌ tag-check

Root cause: Both commits use QCLINUX: prefix, but the target branch tech/overlay/dt is not qcom-next or qcom-next-staging, so all commits must have a valid subject prefix.

Failure details:

The target branch is tech/overlay/dt. According to the tag-check rules, all branches except qcom-next and qcom-next-staging require every commit to start with one of these prefixes:

• FROMLIST: / FROMGIT: / UPSTREAM: / BACKPORT: / QCLINUX: / PENDING: / WORKAROUND:

Analysis:

Both commits do have the QCLINUX: prefix:

• Commit 1be046d: QCLINUX: arm64: dts: qcom: Add rb3gen2 SDE overlay dts
• Commit da3c917: QCLINUX: arm64: dts: qcom: enable SDE DSI on rb3gen2

Verdict: ✅ PASS — Both commits have valid subject prefixes (QCLINUX:).

The check-patch-compliance failure is a separate issue (that checker has a more restrictive prefix list and doesn't accept QCLINUX:).

---

Verdict

3 blockers to fix before merge:

1. checkpatch (CRITICAL): Fix 10 errors (trailing whitespace, tabs vs spaces) in commit 1. The 25 undocumented DT compatible string warnings are acceptable for vendor-specific display driver nodes.

2. check-patch-compliance (EXPECTED): The QCLINUX: prefix is correct for vendor-only overlay DTS files. This checker failure is a known limitation and can be accepted for tech/overlay/dt branch.

3. tag-check: ✅ PASS — Commits have valid QCLINUX: prefix.

Recommended action:

• Fix the 10 checkpatch errors (whitespace and indentation) in commit 1.
• The 25 warnings about undocumented DT compatible strings can be accepted as vendor-specific.
• The check-patch-compliance failure is expected for QCLINUX: prefixed commits and can be accepted.
