.htaccess Redirect Specific Subdomain from HTTPS back to HTTP

I am using .htaccess to redirect all requests (except to subdomains) from HTTP to HTTPS. This code works for me just fine: 

RewriteCond %{HTTPS} off
RewriteCond %{HTTP_HOST} !=m.example.com
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI}

However, it does not prevent the user from manually attempting to access the subdomain using the HTTPS (The SSL that I have does not cover subdomains and shows trust error when used for sub-domains).

Now, I am wondering:

1-How can I redirect all HTTPS requests to subdomain back to HTTP?

2-How can I modify this code to dynamically apply the subdomain restrictions to other subdomains (not only m.example.com)

1) If the certificate doesn't include m.example.com, you can never send the redirect, since the browser will refuse to make a connection. So there is no way of doing this.

2) So all you want the htaccess to do is redirect the naked domain to https. To do this use:

RewriteCond %{HTTPS} off
RewriteCond %{HTTP_HOST} ^example.com$
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI}

I case the certificate also includes www.example.com use

RewriteCond %{HTTPS} off
RewriteCond %{HTTP_HOST} ^(www.)?example.com$
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI}
