Subject: [PATCH 0/1] Add node availability check for child node iteration on ACPI fwnode backend

Hello everyone,

This patch adds device node availability check to the child device node
iteration in the ACPI fwnode backend.

The previous set including with the tree-wide changes can be found here
<URL:https://lore.kernel.org/linux-acpi/CAJZ5v0gQ9vnT+Z8zryEausp-2xX7HocoBgwmiptxg7BGiU9C8g@mail.gmail.com/T/#t>.
I'll post the other bits separately as they'll be merged at different
moments. The rest of the ACPI changes can also wait until v6.19.

since tree-wide set v2
<20250924074602.266292-1-sakari.ailus@...ux.intel.com>, WRT. this patch:

- Don't use kernel-doc functions to document static functions in .c files.

- Add empty lines between sections within a now non-kernel-doc comment.

since v1 <20250916160129.3955410-1-sakari.ailus@...ux.intel.com> (entire
tree-wide set):

- Move patch "ACPI: property: Make acpi_get_next_subnode() static" as
  first.

- Add missing parentheses and kernel-doc Return: section in
  acpi_get_next_present_subnode() documentation and move the Return
  section: of fwnode_graph_get_endpoint_by_id() to the end of the
  documentation section (new patch for the latter).

- Use device_get_next_child_node() instead of fwnode_get_next_child_node()
  in flash LED driver drivers.

- Rework iterating port nodes in acpi_graph_get_next_endpoint() as
  suggested by Andy (new patch).
