Trailing slash on void elements

After posting a new blog page/post, I always use validator.w3.org to verify. Lately, they have been flagging this as “Info”:

“Trailing slash on void elements has no effect and interacts badly with unquoted attribute values.”

Can you please remove the slash “/>” and make it like this “>” for these html elements:
<meta, <link, <input, <img.

I know it’s not an error, but the more of these “Info” comments I can remove, the better it is. Thanks.
