The issues raised by you were acknowledged as being valid, however they were not deemed important enough to stop inclusion in wireless-next and net-next. However, it is good to see that you have put effort in providing a patch series for these issues. Now, since I believe that it is better to work with people, rather than against them, would it be possible to post this patch series somewhere as a set of separate patches, so that they can be reviewed as such? --- Gertjan rt2x00 project developer > > Namely, it: > > - Adds abstraction of chipset register access for chipsets connected to > different buses by using new structure (struct rt2800_ops) which contains > all needed register access methods. > > [ It is a prerequisite for fixing code duplication between rt2800usb.c > and rt2800pci.c drivers. ] > > - Fixes code duplication in rt2800usb.h and rt2800pci.h header files by > using new shared rt2800.h header (almost 1800 LOC gone). > > Updated debugging scripts are located here: > > http://www.kernel.org/pub/linux/kernel/people/bart/rt2800/scripts/ > > (they also work fine with older drivers) > > - Adds rt2800 library containing common code for PCI and USB versions > of rt2800 chipsets.
