Works for me, thanks!
Tested-by: Thomas Renninger <trenn@...e.de>

Is this supposed to go into 2.6.33 still?
Do you consider this save enough to CC: stable@...nel.org and just
push it/commit it there?
I can confirm that this one patches and works fine for 2.6.32.
2.6.31 would also need this fix, the regression was introduced somewhere
between 2.6.30 and 2.6.31.

Thanks again,

    Thomas
