Subject: [PATCH v2 3/7] tty: Partially fix kernel-docs layout
Currently a bunch of the kernel-docs function comments contain custom
layout. We should use the standard kernel-docs function comment layout
as per Documentation/doc-guide/kerenl-doc.rst
Fix layout in kernel-docs to be kernel standard.
Signed-off-by: Tobin C. Harding <tobin@...nel.org>
---
Subject line contains 'Partially' because a later patch fixes the
section format which is still part of the layout.
