Would you mind using the correct eh_X callbacks here?
LUN Reset is _not_ identical to TARGET Reset (conceptually, at
least). And I'm currently trying to disentangle those;
idea is to have the actual device as the argument, not the command.
Having yet another driver which mangles those only serves to
increase the patch here ...
Thanks.
