The cmd->timeout field has been obsolete for a while now.  While looking
to remove it, I came across this use in the aacraid driver.  It looks
like you want to initialise the firmware with the current timeout of the
command (in seconds), so the value I think you should be using is
cmd->timeout_per_command.
