To make sure, it doesn't mean to send the patch to stable tree.
See below.

A slight fuzz can be resolved by patch program.  I guess 3.1 patch
is applicable to 3.0 in your case.

Just try to apply the same patch to 3.0 before submission.  If it's
applied without error, put "Cc: stable at kernel.org" line after your
Signed-off-by line in the change log text.  When this line is added,
you don't have to send it via e-mail.  Greg will pick it up
automatically when it's merged to the Linus tree.  This is the
preferred way than sending patches individually to stable at kernel.org
via e-mail.

Prepare and send e-mail to stable at kernel.org only when 3.1 patch isn't
applicable and a different patch is mandatory for 3.0 kernel.
This process begins _after_ the patch is merged to Linus tree.
In that case, don't forget to give the corresponding upstream commit
it of the patch, too.
