Thanks for picking up this series.

Sashiko report a minor issue that I should not use scoped_guard inside
a function has goto.

Actually it is not an bug. The goto logic and the scoped area are not mixed,
but anyway I just posted out v3 to address the issue:
https://lore.kernel.org/all/20261007-regmap-lock-2nd-v3-0-0e590c4125be@xxxxxxx/

If you would keep v2, I could post a incremental patch to address the
Sashiko's findings. Or you may pick v3.

Thanks
Peng
