Oh OK... then atleast there is something wrong with the naming of Björns patches as they are 8xxx and your chips are also named 8xxx ... Anyway I will create a patch to move the current msm driver down to a folder named "qcom" and we can atleast collect these drivers in a single place since the chipsets are related, OK? Then I guess even if the chips are totally unrelated it'd be interesting to have you two guys cross-review each other's drivers so the behaviour is consistent across qualcomm platforms.
