[PATCH] ieee1394: schedule for removal

[PATCH] ieee1394: schedule for removal

[Stefan Richter]

All application domains that are supported by the old ieee1394 driver
stack are supported by the newer firewire driver stack too.  (FireWire
audio came last, in 2.6.32.)  There is now good and extensive experience
with the newer stack from deployment in Fedora since F7 as well as by
enthusiast users of other distributions.  The new drivers have
consequently been recommended as the default ones since 2.6.33, in order
to fix some severe usability problems of FireWire on Linux due to
limitations of the old stack.  It is now high time to announce when the
obsolete drivers will be removed.

Removal in 2.6.36 should be OK too, but one of the Linux FireWire audio
driver (ffado) developers recommended 2.6.37 since the current
generation of pro-audio oriented distributions still ships the old
drivers as default.
