Hard to read. I hope I did not miss an important comment.

No, it is what it tells: a workaround.
If you undef COMMAND_TIMEOUT_WORKAROUND, command timeout errors will
happen after some time. The workaround will be removed when the problem
has been identified and fixed.

ACK, should be fixed.
Apparently some people spend their time renaming constants. :-)

Mauro, I did not write the code, and I think a developer has the right
to choose the implementation he likes. It is hard enough that we have to
respect, what checkpatch.pl forces us to do.
Matthias spent a considerable amount of time to reformat the code for
that questionable kernel coding style. But now it is enough, let's
focus on bugs.
Sorry, I will not change any of these non-issues, and I will not sign a
changeset which replaces 'x += 1' by 'x++' (or something like that).
If you think it is essential, prepare a changeset by yourself.
CU
Oliver
