Subject: [PATCH 01/29] coding-style.rst: Avoid comma statements

Commas are not how statements are terminated.
Always use semicolons and braces if necessary.

 Don't put multiple assignments on a single line either.  Kernel coding style
 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.
