I observed on the repo https://github.com/steev/linux with the branch "linux-v5.19.0-rc8-tests" doesn't contain the latest patch set for "interconnect: qcom: icc-rpm: Support bucket", it contains patch:
https://github.com/steev/linux/commit/20386c070c2d12a74092d72aef1c8be37a5f5177
We can compare with Greg's char-misc.git branch, it contains patch: https://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc.git/commit/drivers/interconnect/qcom/icc-rpm.c?h=char-misc-testing&id=e3305daad62c90068e755cdae36a86ac4f02af22
I don't know how these old version patches have been merged to the repo https://github.com/steev/linux, but it's good to sync with latest patch set.
Thanks, Leo
