[PATCH 0/2] libgpiod: Minor fixups for 2.0 bindings

[Viresh Kumar]

Hi Bartosz,

This patchset contain minor fixes for the libgpiod 2.0 helpers that I found
during my rust bindings work with it.

It is based on next/post-libgpiod-2.0 branch.

[PATCH 1/2] libgpiod: Fix ioctl number for gpiod_line_request_reconfigure_lines()

[Viresh Kumar]

The ioctl number used for gpiod_line_request_reconfigure_lines() is
incorrect written as GPIO_V2_LINE_GET_VALUES_IOCTL instead of
GPIO_V2_LINE_SET_CONFIG_IOCTL. Fix it.

[PATCH 2/2] libgpiod: Remove dummy declaration gpiod_line_config_get_event_clock()

[Viresh Kumar]

gpiod_line_config_get_event_clock() isn't implemented, and just has the
declaration available. Drop it.

Thanks a lot! Are you fine with me squashing this with the big patch
like I did with similar fixes from Ben before? The patch is
technically still under development (this kind of bugs will be
uncovered a lot once I start writing tests) and there's no reason to
merge it into master with bugs. I would keep your signed-off-by of
course.

Its okay to drop that as well if required, I don't care about it much :)

But we want this function - it should get implemented, not dropped. :)

It's actually added in the devel branch for line_config accessors.
