6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Melissa Wen <mwen@xxxxxxxxxx>
[ Upstream commit 94369589e4ec13c762fe10a1fdc4463bdfee5d5f ]
This function has many conditions and all code style issues (identation,
missing braces, etc.) make reading it really annoying.
