The patch is good because this is in line with Rusty Russells API
manifesto:

7. The obvious use is (probably) the correct one.
6. The name tells you how to use it.

It doesn't apply to my "devel" branch as of now:
https://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio.git/log/?h=devel

If you rebase this and the next patch and send them separately I
am willing to apply them already for v5.4 to easy your refactoring
work during the v5.5 cycle here, provided we try to fix up the old users
ASAP and delete the compatibility fallbacks in the near future.

Yours,
