Linus announced last week that the merge window for 2.6.21 was closed, so it gave me some time to continue improving the zr364xx driver.So I posted a small patch 2 days ago to do some cleanup as suggested by Mauro, and I also fixed a little issue.
Today, Mauro posted a message on the LKML asking Linus if he agrees to include some updates for 2.6.21 despite the freeze, including my work :)
So let's see...
Update #1: it is now in Andrew Morton's branch.
Update #2: my zr364xx tree will now be hosted here.
