From: Corey Minyard <cminyard@mvista.com>


The priv->cmd is called subcmd elsewhere, and that's a more
appropriate name for it, so rename it.

The "size" parameter passed in to i801_access is passed to other
functions and those name is "command".  This is confusing with the
"command" parameter passed in to i801_access.  Rename it to "size"
everywhere.
