Don't use commas to avoid using braces:
.. code-block:: c
if (condition)
do_this(), do_that();
Always uses braces for multiple statements:
.. code-block:: c
if (condition) {
do_this();
do_that();
}

is super simple. Avoid tricky expressions.
Outside of comments, documentation and except in Kconfig, spaces are never
used for indentation, and the above example is deliberately broken.
