With v6.13-rc2 and Fabien's regmap/regulator/I2C on top I gave it a
try on x86 with qemu. Additionally cross compiled for arm64 and will
try it on real hardware once I have it available. But previous
versions of this series have been fine on that, already. No issues
observed for running the samples and for the examples/KUnit. So:
