This is true, but the extra "omapdss" does not cause any issues at the
moment, and the time when it causes issues is still many kernel versions
in the future.

But, yes, thinking about this, I agree, it's better to pick this one
separately as a fix (after rebasing it on top of current maineline so
that it doesn't depend on the toppoly name change), and leaving the
toppoly->tpo change as a cleanup.
