The To: and Cc: list gave me quite some headache. :) Next time I make sure that at least LKML is cc'ed on the whle series so people have a lace to look at it in one thread. > > Understand.

Yeah, pretty similar. We had to start from 2.4 driver code to get in touch with this chip. Motorola did not offer any docs. Also the usual embedded board out-of-tree problem. We are doing a lot better now since the last two kernels though. Better workflow, tools, faster reaction on review and more energy towards upstream submissions. regards Stefan Schmidt -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
