Sorry for the behavior of my mail client, I have unfortunately no
chance to change it.
However, I think you'll prefer this format.

This is currently part of the 2.6.16 mainline! However, I have seen
that this line has been replaced
by "pio = get_irq_chip_data(irq);" in 2.6.17-rc4-genirq4 which access
desc->chip_data. So this problem
has been solved by genirq4...
