This patch series fixes various (mostly harmless) issues introduced by
commit 3027743f83f867d8 ("gpio: Remove VLA from gpiolib").

As per the "one patch should fix one issue"-policy, this series contains 3
patches, although they all have the same Fixes: tag.

Changes compared to v1:
  - Rebase on top of gpio array rework.

Patches applied, thanks Geert!

W.r.t. propagating errors: while gpiod_set_array_value_complex() and its
callers can now return an error code, this is currently limited to -ENOMEM.
Actual failures setting a GPIO output value cannot be propagated, as
gpio_chip.set() still returns void.  Do you want to change that?
E.g. gen_74x164_set_value() can fail.

I think we discussed it at one point and said that it's something
we should fix some day, just nobody has got around to do it.

Yours,
