  Do you mean "not maintained anymore"?

  I'd look into committing it, but it worries me that it patches
mmc/mmc.h. I don't think it should give any compatibility problems for
other hardware, as it just adds more error codes, but it would be
helpful to know that these additions are compatible with 2.6.22, or
something like that. If you can confirm that, or suggest if it's worth
to be committed anyway, please do.
