status? : [PATCH] - tc{set,get}attr() error checking and B0 support

[Troy Curtiss]

Chris,
  Have you have a chance to take a look at my latest patch rounding out the
tc{set,get}attr() support for B230400 (and B0)?  I've been beating on it for
a week and it seems to work correctly wrt. serial port operations.  The only
trouble (which was present before my patch) is errno not getting propagated
back up when the tc{set,get}attr() call fails.  Thanks,

-Troy
