gpio: Fix kernel-doc comments to nested union

[PATCH] gpio: Fix kernel-doc comments to nested union

Posted by Akira Yokosawa 3 years, 10 months ago

Commit 48ec13d36d3f ("gpio: Properly document parent data union")
is supposed to have fixed a warning from "make htmldocs" regarding
kernel-doc comments to union members.  However, the same warning
still remains [1].

Fix the issue by following the example found in section "Nested
structs/unions" of Documentation/doc-guide/kernel-doc.rst.

Gentle ping to gpio maintainers.

I thought this fix would go through brgl's tree.

        Thanks, Akira
