Thanks, as there are things happening in the GPIO subsystem I
have put this one patch on an immutable branch here:
https://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio.git/log/?h=ib-devm-gpiod-get-parent-array
Please ask the maintainer (I guess Lee?) to pull this into wherever
the rest of the patches should be merged if you want patches beyond
this point to be applied for the next (v5.6) merge window, then this
patch is not needed in the series.
Yours,
Linus Walleij
