Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ieee1394/linux1394-2.6
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ieee1394/linux1394-2.6: firewire, ieee1394: update Kconfig help firewire, ieee1394: update MAINTAINERS entries firewire: ohci: always use packet-per-buffer mode for isochronous reception firewire: cdev: fix another memory leak in an error path firewire: fix use of multiple AV/C devices, allow multiple FCP listeners Comments from Stefan: Distributors who still ship the old stack (ieee1394, ohci1394, raw1394, sbp2, eth1394 and more) should now switch to the new one (firewire-core, firewire-ohci, firewire-sbp2, firewire-net). In the first iteration, those distributors might want to ship the old stack also (but blacklisted) as a fallback for their users if unforeseen problems with the newer replacement drivers are encountered. The older FireWire stack contains several known problems which are not going to be fixed; instead, those issues are addressed by the new stack. An incomplete list of these issues is kept in bugzilla: http://bugzilla.kernel.org/show_bug.cgi?id=10046 We have a guide on migration from the older to the newer stack: http://ieee1394.wiki.kernel.org/index.php/Juju_Migration
