* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ieee1394/linux1394-2.6: ieee1394: schedule for removal firewire: core: use separate timeout for each transaction firewire: core: Fix tlabel exhaustion problem firewire: core: make transaction label allocation more robust firewire: core: clean up config ROM related defined constants ieee1394: mark char device files as not seekable firewire: cdev: mark char device files as not seekable firewire: ohci: cleanups and fix for nonstandard build without debug facility firewire: ohci: wait for PHY register accesses to complete firewire: ohci: fix up configuration of TI chips firewire: ohci: enable 1394a enhancements firewire: ohci: do not clear PHY interrupt status inadvertently firewire: ohci: add a function for reading PHY registers Trivial conflicts in Documentation/feature-removal-schedule.txt

----------------------------
|

|

What: old ieee1394 subsystem (CONFIG_IEEE1394)
|
||||
When: 2.6.37
|
||||
Files: drivers/ieee1394/ except init_ohci1394_dma.c
|
||||
Why: superseded by drivers/firewire/ (CONFIG_FIREWIRE) which offers more
|
||||
features, better performance, and better security, all with smaller
|
||||
and more modern code base
