Hi,

✅ All tests passed successfully. No issues detected.
No action required from the submitter.

The upstream commit SHA1 provided is correct: 08f6554ff90ef189e6b8f0303e57005bddfdd6a7

Status in newer kernel trees:
6.15.y | Present (exact SHA1)
6.12.y | Present (exact SHA1)
6.6.y | Present (exact SHA1)
6.1.y | Present (different SHA1: 2995dbfe98e7)
5.15.y | Present (different SHA1: d36719f29376)
5.10.y | Present (different SHA1: 9562b9f708e9)

Note: The patch differs from the upstream commit:

         A future change will move CLANG_FLAGS from KBUILD_{A,C}FLAGS to
         KBUILD_CPPFLAGS so that '--target' is available while preprocessing.
         When that occurs, the following error appears when building ARCH=mips
