Wrap the assert macros in ({ ... }) so they can be safely used both as right side argument as well as in conditionals without curly brackets around them. In the process, find a bunch of missing semicolons, fix them. Reviewed-by: Simon Glass <sjg@chromium.org> Signed-off-by: Marek Vasut <marek.vasut+renesas@mailbox.org>
