[U-Boot] WARNING: space prohibited between function name and open parenthesis '('

I'm getting a lot of the following when running checkpatch:

WARNING: space prohibited between function name and open parenthesis '('

Should I ignore these?

So far, I've written completely new code such that it doesn't trigger this warning, but where editing existing code (e.g. just changing the name of a function), I've avoided fixing this checkpatch warning so it's more obvious what my diff is doing; equally, fixing this would cause the lines I edit to be inconsistent with those around them.

Any guidance appreciated. Thanks.
