6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Carlos Llamas <cmllamas@xxxxxxxxxx>
commit f92a59f6d12e31ead999fee9585471b95a8ae8a3 upstream.
For ${atomic}_sub_and_test() the @i parameter is the value to subtract,
not add. Fix the typo in the kerneldoc template and generate the headers
with this update.
Fixes: ad8110706f38 ("locking/atomic: scripts: generate kerneldoc comments")
